General Information
Reliability
The Mean Time Between Failure (MTBF) is calculated at
full output power and an operating ambient temperature
(TA) of +40°C, which is a typical condition in Information
and Communication Technology (ICT) equipment. Different
methods could be used to calculate the predicted MTBF
and failure rate which may give different results. Ericsson
Power Modules currently uses Telcordia SR332.
Predicted MTBF for the series is:
- 1.5 million hours according to Telcordia SR332,
issue 1, Black box technique.
Telcordia SR332 is a commonly used standard method
intended for reliability calculations in ICT equipment. The
parts count procedure used in this method was originally
modelled on the methods from MIL-HDBK-217F, Reliability
Predictions of Electronic Equipment. It assumes that no
reliability data is available on the actual units and devices
for which the predictions are to be made, i.e. all predictions
are based on generic reliability parameters.
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Ericsson
Power Modules products include:
- Lead in high melting temperature type solder (used to
solder the die in semiconductor packages)
- Lead in glass of electronics components and in
electronic ceramic parts (e.g. fill material in chip
resistors)
- Lead as an alloying element in copper alloy containing
up to 4% lead by weight (used in connection pins
made of Brass)
Quality Statement
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, 6σ (sigma), and SPC are intensively in use
to boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
work force, contribute to the high quality of our products.
Warranty
Warranty period and conditions are defined in Ericsson
Power Modules General Terms and Conditions of Sale.
Limitation of Liability
Ericsson Power Modules does not make any other
warranties, expressed or implied including any warranty of
merchantability or fitness for a particular purpose
(including, but not limited to, use in life support
applications, where malfunctions of product can cause
injury to a person’s health or life).

On-board DC-DC converters and DC/DC regulators are
defined as component power supplies. As components
they cannot fully comply with the provisions of any Safety
requirements without “Conditions of Acceptability”.
Clearance between conductors and between conductive
parts of the component power supply and conductors on
the board in the final product must meet the applicable
Safety requirements. Certain conditions of acceptability
apply for component power supplies with limited stand-off
(see Mechanical Information for further information). It is
the responsibility of the installer to ensure that the final
product housing these components complies with the
requirements of all applicable Safety standards and
Directives for the final product.
Component power supplies for general use should comply
with the requirements in IEC60950, EN60950 and UL60950
“Safety of information technology equipment”.
There are other more product related standards, e.g.
IEEE802.3af “Ethernet LAN/MAN Data terminal equipment
power”, and ETS300132-2 “Power supply interface at the
input to telecommunications equipment; part 2: DC”, but all
of these standards are based on IEC/EN/UL60950 with
regards to safety.
Ericsson Power Modules DC/DC converters and DC/DC
regulators are UL60950 recognized and certified in
accordance with EN60950.
The flammability rating for all construction parts of the
products meets requirements for V-0 class material
according to IEC 60695-11-10.
The products should be installed in the end-use equipment,
in accordance with the requirements of the ultimate
application. Normally the output of the DC/DC converter is
considered as SELV (Safety Extra Low Voltage) and the
input source must be isolated by minimum Double or
Reinforced Insulation from the primary circuit (AC mains) in
accordance with IEC/EN/UL60950.
Isolated DC/DC converters
It is recommended that a slow blow fuse with a rating twice
the maximum input current per selected product be used at
the input of each DC/DC converter. If an input filter is used
in the circuit the fuse should be placed in front of the input
filter.
In the rare event of a component problem in the input filter
or in the DC/DC converter that imposes a short circuit on
the input source, this fuse will provide the following
functions:
• Isolate the faulty DC/DC converter from the input
power source so as not to affect the operation of
other parts of the system.
• Protect the distribution wiring from excessive
current and power loss thus preventing hazardous
overheating.
The galvanic isolation is verified in an electric strength test.
The test voltage (Viso) between input and output is
1500 Vdc or 2250 Vdc for 60 seconds (refer to product
specification).
Leakage current is less than 1 µA at nominal input voltage.
24 V DC systems
The input voltage to the DC/DC converter is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.
48 and 60 V DC systems
If the input voltage to the DC/DC converter is 75 Vdc or
less, then the output remains SELV (Safety Extra Low
Voltage) under normal and abnormal operating conditions.
Single fault testing in the input power supply circuit should
be performed with the DC/DC converter connected to
demonstrate that the input voltage does not exceed
75 Vdc.
If the input power source circuit is a DC power system, the
source may be treated as a TNV2 circuit and testing has
demonstrated compliance with SELV limits and isolation
requirements equivalent to Basic Insulation in accordance
with IEC/EN/UL60950.
Non-isolated DC/DC regulators
The input voltage to the DC/DC regulator is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.

normally tested with one parameter at a time exceeding the limits in the Electrical Specification. If exposed to stress above these limits, function and performance
may degrade in an unspecified manner.

Layout recommendations
The radiated EMI performance of the product will depend on
the PCB layout and ground layer design. It is also important
to consider the stand-off of the product. If a ground layer is
used, it should be connected to the output of the product and
the equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.
Output ripple and noise
Output ripple and noise measured according to figure below.
See Design Note 022 for detailed information.
Output ripple and noise test setup
Operating information
Extended information for POLA products is found in
Application Note 205.
Input Voltage
The input voltage range 8 to 14 Vdc makes the product easy
to use in intermediate bus applications when powered by a
non-regulated bus converter or a regulated bus converter.
Turn-off Input Voltage
The products monitor the input voltage and will turn on and
turn off at predetermined levels.
The typical hysteresis between turn on and turn off input
voltage is 0.5V.
Turn on/off voltage can be adjusted by using UVLO
(Undervoltage lockout) function. The UVLO character is
defined by the ON threshold (VTHD) voltage. Below the ON
threshold, the Inhibit control is overridden, and the module
does not produce an output.
The UVLO feature allows for limited adjustment of the ON
threshold voltage. It is made by using a single resistor
between the Inhibit/UVLO pin (pin 21) and ground pins (pin
8,9,12,13). The VTHD value can be adjusted from 8.0V to
11V. Default value of VTHD is 7.2V.
Below equation determines the value of resistor required to
adjust VTHD to a new value.

Inhibit Control
The products are fitted with
a remote control function
by using the Inhibit/UVLO
pin. The Inhibit control
function allows the product
to be turned on/off by an
external device like a
semiconductor or
mechanical switch. The RC
pin has an internal pull up.
An external pull-up resistor
should never be used with
the inhibit pin.
When the Inhibit pin is left open, the regulator will turn on
when the input voltage is applied. Turn off is achieved by
connecting the Inhibit pin to the GND.
The reference figure above shows the typical application of
the inhibit function. The input is not compatible with TTL logic
device. An open-collector (or open-drain) discrete transistor is
recommended for control. Turning the discrete transistor on
applies a low voltage to the Inhibit control pin and disables the
output of the module. If this device is then turned off, the
module executes a soft-start power-up sequence. A regulated
output voltage is produced within 20 ms.
External Decoupling Capacitors
Input capacitors:
The PMR 8210 requires a minimum input capacitance of e
1000 µF. The ripple current rating of the input capacitor must
be at least 750 mA rms. An optional 22 µF X5R/X7R ceramic
capacitor is recommended to reduce RMS ripple current.
The size and value of the input capacitor is determined by the
converter’s transient performance capability. This minimum
value assumes that the converter is supplied with a
responsive, low inductance input source. This source should
have ample capacitive decoupling, and be distributed to the
converter via PCB power and ground planes.
Ceramic capacitors should be located as close as possible to
the module's input pins, within 0.5 inch (1,3 cm). Adding
ceramic capacitance is necessary to reduce the high-
frequency ripple voltage at the module's input. This reduces
the magnitude of the ripple current through the electrolytic
capacitor, as well as the amount of ripple current reflected
back to the input source. Additional ceramic capacitors can be
added to further reduce the RMS ripple current requirement
for the electrolytic capacitor.
The main considerations when selecting input capacitors are
the RMS ripple current rating, temperature stability, and less
than 100 m of equivalent series resistance (ESR).
Regular tantalum capacitors are not recommended for the
input bus. These capacitors require a recommended
minimum voltage rating of 2× (maximum dc voltage + ac
ripple). This is standard practice to ensure reliability. No
tantalum capacitors were found with a sufficient voltage rating
to meet this requirement.
Output capacitors:
The PMR 8210 module requires a minimum output
capacitance of 1000µF of polymer-aluminum, tantulum, or
polymer-tantalum type.
The required capacitance above the minimum is determined
by actual transient deviation requirements. See
“TurboTrans Technology” information below.
For both input and output capacitors, when the operating
temperature is below 0°C, the ESR of aluminium electrolytic
capacitors increases. For these applications, OS-CON, poly-
aluminium, and polymer-tantalum types should be considered.
If the TurboTrans feature is not used, minimum ESR and
maximum capacitor limits must be followed. System stability
may be effected and increased output capacitance may be
required without TurboTrans.
When using the PMR 8210, observe the minimum ESR of the
entire output capacitor bank. The minimum ESR limit of the
output capacitor bank is 7m.
When using PMR 8210 without the TurboTrans feature, the
maximum amount of capacitance is 1000 µF of ceramic type.
Large amounts of capacitance may reduce system stability.
Utilizing the TurboTrans feature improves system stability,
improves transient response, and reduces the amount of
output capacitance required to meet system transient design
requirements. For detaile information, see “TurboTrans
Technology” information below .
Output Voltage Adjust (Vadj)
The product has an Output Voltage Adjust function. The
function can be used to adjust the output voltage in the range
from 3.0V to 5.25V.
The Vo Adjust control sets the output voltage of the PMR
8210. The adjustment method requires the addition of a single
external resistor, RSET, that must be connected directly
between pins Vo Adjust (pin 18) and AGND (pin 4). The value
of the required resistor can be calculated using the following
formula.

resistor directly between pins 18 and 4, as close to the
regulator as possible, using dedicated PCB traces.
(2) Never connect capacitors from Vo Adjust to either +
Sense, GND, or Vo. Any capacitance added to the Vo Adjust
pin affects the stability of the regulator.
(3) For output voltages less than 1.2 V, the output ripple may
increase (up to 2 ) when operating at input voltages greater ×
than (Vo 12). Adjusting the switching frequency using the ×
SmartSync feature may increase or decrease this ratio.
Parallel Operation
The PMR 8210 module is capable of being configured in
parallel with another PMR 8210 module to share load current.
To parallel the two modules, it is necessary to configure one
module as the Master and one module as the Slave. To
configure a module as the Master, connect the CONFIG pin
(pin 1) to GND. The CONFIG pin of the Slave must be
connected to VI. In order to share current, pins 2 through 5 of
both the Master and Slave must be connected between the
two modules. The module that is configured as the MASTER
is used to control all of the functions of the two modules
including Inhibit, ON/OFF control, AutoTrack sequencing,
TurboTrans, SmartSync, +/- Remote Sense, and Output
Voltage Adjust.
The MASTER and the SLAVE must be powered from the
same input voltage supply.
When using TurboTrans while paralleling two modules, the
TurboTrans resistor, RTT, must be connected from the
TurboTrans pin (pin 19) of the Master module to the +Sense
pin (pin 17) of the Master module. When paralleling modules
the procedure to calculate the proper value of output
capacitance and RTT is similar to that explained in the
TurboTrans Selection section, however the values must be
calculated for a single module. Therefore, the total output
current load step must be halved before determining the
required output capacitance and the RTT value as explained
in the TurboTrans Selection section. The value of output
capacitance calculated is the minimum required output
capacitance per module and the value of RTT must be
calculated using this value of output capacitance. The
TurboTrans pin of the Slave module must be left open.
Current sharing layout
In current sharing applications the VI pins of both modules
must be connected to the same input bus. The VO pins of
both modules are connected together to power the load. The
GND pins of both modules are connected via the GND plane.
Four other inter-connection pins are connected between the
modules. Below figure shows the required layout of the inter-
connection pins for two modules configured to share current.
Notice that the Share (pin 2) connection is routed between the
Comp (pin 3) and CLKIO (pin 5) connections. AGND (pin 4)
should be connected as a thicker trace on an adjacent layer,
running parallel to pins 2, 3 and 5. AGND must not be
connected to the GND plane.
Remote Sense
The products have remote sense that can be used to
compensate for voltage drops between the output and the
point of load. The sense traces should be located close to the
PCB ground layer to reduce noise susceptibility. The remote
sense circuitry will compensate for up to 0.3 voltage drop
between output pins and the point of load.
If the remote sense is not needed +Sense should be
connected to +Out and –Sense should be connected to –Out.
Over Temperature Protection (OTP)
The regulators are protected from thermal overload by an
internal over temperature shutdown circuit. If the internal
temperature exceeds the OTP threshold, the module’s inhibit
control is internally pulled low. This turns the output off. The
voltage drops as the external output capacitors are discharged
by the load circuit. The product will make continuous attempts
to start up (non-latching mode) and resume normal operation
automatically when the temperature has dropped >10°C below
the temperature threshold.

Over Current Protection (OCP)
The regulators include current limiting circuitry for protection at
continuous overload. The output voltage will decrease towards
zero for output currents in excess of max output current (max
IO). The regulator will resume normal operation after removal
of the overload. The load distribution should be designed for
the maximum output short circuit current specified.
Soft-start Power Up
From the moment a valid input voltage is applied, the soft-start
control introduces a short time-delay (typically 5-15 ms) before
allowing the output voltage to rise. The initial rise in input
current when the input voltage first starts to rise is the charge
current drawn by the input capacitors.
Auto-Track™ Function
Auto-Track was designed to simplify the amount of circuitry
required to make the output voltage from each unit power up
and power down in sequence. The sequencing of two or more
supply voltages during power up is a common requirement for
complex mixed-signal applications, that use dual-voltage VLSI
Ics such as DSPs, micro-processors and ASICs.
Notes on Use of Auto-Track™
1. The Track pin voltage must be allowed to rise above the
module set-point voltage before the module regulates at its
adjusted set-point voltage.
2. The Auto-Track function tracks almost any voltage ramp
during power up, and is compatible with ramp speeds of up to
1 V/ms.
3. The absolute maximum voltage that may be applied to the
Track pin is the input voltage VI.
4. The module cannot follow a voltage at its track control
input until it has completed its soft-start initialization.
This takes about 20 ms from the time that a valid voltage has
been applied to its input. During this period, it is
recommended that the Track pin be held at ground potential.
5. The Auto-Track function is disabled by connecting the
Track pin to the input voltage (VI). When Auto-Track is
disabled, the output voltage rises according to its softstart
rate after input power has been applied.
6. The Auto-Track pin should never be used to regulate the
module’s output voltage for long-term, steady-state
operation.
Smart Sync
Smart Sync is a feature that allows multiple power modules to
be synchronized to a common frequency. When not used, this
pin must be connect to GND. Driving the Smart Sync pins with
an external oscillator set to the desired frequency,
synchronizes all connected modules to the selected requency.
The synchronization frequency can be higher or lower than the
nominal switching frequency of the modules within the range
of 240 kHz to 400 kHz.
Synchronizing modules powered from the same bus
eliminates beat frequencies reflected back to the input supply,
and also reduces EMI filtering requirements. Eliminating the
low beat frequencies (usually<10kHz) allows the EMI filter to
be designed to attenuate only the synchronization frequency.
Power modules can also be synchronized out of phase to
minimize ripple current and reduce input capacitance
requirements.
The PMR 8210 requires that the external synchronization
frequency be present before a valid input voltage is present or
before release of the inhibit control.
Pre-Bias Startup Capability
A prebias startup condition occurs as a result of an external
voltage being present at the output of a power module prior to
its output becoming active.This often occurs in complex digital
systems when current from another power source is backfed
through a dual-supply logic component, such as FPGA or
ASIC.
The PMR family of regulators incorporate synchronous
rectifiers, but will not sink current during startup, or whenever
the Inhibit pin is held low. However, to ensure satisfactory
operation of this function, certain conditions must be
maintained.
For more inforamtion, please refer to Application Note 205.
Turbo TransTM Technology
Turbo TransTM optimizes the transient response of the
regulator with added external capacitance using a single
external resistor. The benefits of this technology include:
reduced output capacitance, minimized output voltage
deviation following a load transient, and enhanced stability
when using ultra-low ESR output capacitors. The amout of
output capacitance required to meet a target output voltage
deviation, is reduded with Turbo TransTM activated. Likewise,
for a given amout of output capacitance, with Turbo TransTM
engaged, the amplitude of the voltage deviation following a
load transient is reduced. Applications requiring tight transient
voltage tolerances and minimized capacitor footprint area
benefit from this technology.
Utilizing Turbo TransTM requires connecting a resistor, RTT ,
between the +Sense pin (pin 17) and the Turbo TransTM pin
(pin 19), The value of the resistor directly corresponds to the
amount of output capacitance required. For the PMR 8210,
the minimum required capacitance is 1000µF. When using
Turbo TransTM, capacitors with a capacitance×ESR product
below 10,000 µF×m are required.
To have a better understanding of the required capacitors with
Turbo TransTM, three types of capacitors are defined as below.

transient voltage deviation per amp of transient load setp.
Select 4mV/A on the Y-axis and read across to the “With
TurboTrans” plot. Following this point down to the X-axis gives
us a minimum required output capacitance of approximately
1700µF. The required RTT resistor value for 1700µF can then
be calculated or selected from the below table. The required
RTT resistor is approximately 31.6K.
To see the benefit of Turbo TransTM, follow the 4mV/A marking
across to the “Without TurboTrans” plot. Following that point
down shows that you would need a minimum of 5500µF of
output capacitance to meet the same transient deviation limit.
This is the benefit of Turbo TransTM .

Thermal Consideration
General
The regulators are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependant on the airflow
across the regulator. Increased airflow enhances the cooling
of the regulator.
The typical Output Current Derating graph can be found in the
Output section for each model provides the available output
current vs. ambient air temperature and air velocity at VI = 12
V.
The product is tested on a 100 x 100 mm double-sided PCB
with 2 oz. copper and the direction of airfow fro pin 10 to pin
22. For surface mount packages, multiple vias must be
utilized.
Definition of product operating temperature
The product operating temperatures is used to monitor the
temperature of the product, and proper thermal conditions can
be verified by measuring the temperature at positions P1, P2,
and P3. The temperature at these positions (TP1, TP2, TP3,)
should not exceed the maximum temperatures in the table
below. The number of measurement points may vary with
different thermal design and topology. Temperatures above
maximum TP1, measured at the reference point P1 are not
allowed and may cause permanent damage.

16 -Sense The sense input allows the
regulation circuit to
compensate for voltage drop
between the module and the
load. The –Sense pin should
always be connected to GND,
either at the load for optimal
voltage accuracy, or at the
module (pin 13).
17 +Sense The sense input allows the
regulation circuit to
compensate for voltage drop
between the module and the
load. The +Sense pin should
always be connected to VO,
either at the load for optimal
voltage accuracy, or at the
module (pin 11).
18 Vo Adjust A 0.05 W 1% resistor must be
directly connected between
this pin and pin4 (AGND) to
set the output voltage to a
value higher than 0.7 V. The
temperature stability of the
resistor should be 100
ppm/℃ (or better). The
setpoint range for the output
voltage is from 0.7V to 3.6V.
If left open circuit, the output
voltage defaults to its lowest
value. For further information,
refer to the information for
each output voltage sector.
19 Turbo TransTM This input pin adjusts the
transient response of the
regulator. To activate the
Turbo TransTM feature, a 1%,
50mW resistor must be
connected between this pin
and pin 17 (+Sense) very
close to the module. For a
given value of output
capacitance, a reduction in
peak output voltage deviation
is achieved by using this
feature. If unused, this pin
must be left open-circuit.
External capacitance must
never be connected to this
pin. The resistance

20 Track This is an analog control inpu
t
that enables the output
voltage to follow an external
voltage. This pin becomes
active typically 25 ms after
the input voltage has been
applied, and allows direct
control of the output voltage
from 0 V up to the nominal
set-point voltage. Within this
range the module’s output
voltage follows the voltage at
the Track pin on a volt-for-volt
basis. When the control
voltage is raised above this
range, the module regulates
at its set-point voltage. The
features allows the output
voltage to rise simultaneously
with other modules powered
from the same input bus. If
unused, this input should be
connected to VI .
NOTE: Due to the
undervoltage lockout feature,
the output of the module
cannot follow its own input
voltage during power up. For
more information, see the
related application note.
21 Inhibit and UVLO The Inhibit pin is an open-
collector/drain, negative logic
input that is referenced to
GND. Applying a low level
ground signal to this input
disables the module’s output
and turns off the output
voltage. When the Inhibit
control is active, the input
current drawn by the
regulator is significantly
reduced. If the Inhibit pin is
left open-circuit, the module
produces an output whenever
a valid input source is
applied.
This pin is also used for input
undervoltage lockout(UVLO)
programming. Connecting a
resistor from this pin to GND
(pin 13) allows the ON
threshold of the UVLO to be
adjusted higher than the
default value. For more
information, see related
application information.
22 SmartSync This input pin sychronizes the
switching frequency of the
module to an external clock
frequency. The SmartSync
feature can be used to
sychronize the switching
frequency of multiple
modules, aiding EMI noise
suppression efforts. The
external synchronization
frequency must be present
before a valid input voltage is
present, or before the release
of inhibit control. If unused,
this pin MUST be connected
to GND. For more
information, please see the
related application note.

bags according to IPC/JEDEC standard J-STD-033A (Handling, packing, shipping, and use of moisture/reflow sensitivity surface
mount devices).
Using products in high temperature Pb-free soldering processes requires dry pack storage and handling. In case the products
have been stored in an uncontrolled environment and no longer can be co nsidered dry, the modules must be baked according
to the referred IPC/JEDEC standard.
