Description
The 9-36V ProLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 3A of output current.
These modules operate over an extra wide range of input voltage (VIN = 9Vdc–36Vdc) and provide a precisely regulated output
voltage from 3Vdc to 18Vdc, programmable via an external resistor. Two new features added with this family of products are
the ability to externally tune the voltage control loop and a variable current limit inversely dependent on output voltage. Other
features include remote On/Off, adjustable output voltage, over current and overtemperature protection. The Tunable LoopTM,
allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output
capacitance leading to savings on cost and PWB area and AutoLimit enables the module to deliver the max possible output
power across the entire voltage range.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part
of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum
safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating
of 8 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc
input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further
information.

Design Considerations
Input Filtering
The 9-36V ProLynxTM module should be connected to a low
ac-impedance source. A highly inductive source can affect
the stability of the module. An input capacitance must be
placed directly adjacent to the input pin of the module, to
minimize input ripple voltage and ensure module stability.
To minimize input voltage ripple, ceramic capacitors are
recommended at the input of the module. Figure 28 shows
the input ripple voltage for various output voltages at
maximum load current with 2x10 µF or 3x10 µF ceramic
capacitors and an input of 12V while Fig. 29 shows the input
ripple for an input voltage of 28V.

Output Filtering
The 9-36V ProLynxTM modules are designed for low output
ripple voltage and will meet the maximum output ripple
specification with 0.1 µF ceramic and 10 µF ceramic capacitors
at the output of the module. However, additional output
filtering may be required by the system designer for a number
of reasons. First, there may be a need to further reduce the
output ripple and noise of the module. Second, the dynamic
response characteristics may need to be customized to a
particular load step change.
To reduce the output ripple and improve the dynamic response
to a step load change, additional capacitance at the output
can be used. Low ESR polymer and ceramic capacitors are
recommended to improve the dynamic response of the
module. Figures 6 and 7 provides output ripple information for
different external capacitance values at various Vo and for full
load currents. For stable operation of the module, limit the
capacitance to less than the maximum output capacitance as
specified in the electrical specification table. Optimal
performance of the module can be achieved by using the
Tunable LoopTM feature described later in this data sheet.

Safety Considerations
For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards, i.e., UL
60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN EN 60950-1:2006
+ A11 (VDE0805 Teil 1 + A11):2009-11; EN 60950-1:2006 +
A11:2009-03.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the input must
meet SELV requirements. The power module has extra-low
voltage (ELV) outputs when all inputs are ELV.
The input to these units is to be provided with a fast-acting
fuse with a maximum rating of 8A in the positive input lead.

Feature Descriptions
Remote Enable
The 9-36V ProLynxTM modules feature an On/Off pin for remote
On/Off operation. Two On/Off logic options are available. In the
Positive Logic On/Off option, (device code suffix “4” – see
Ordering Information), the module turns ON during a logic High
on the On/Off pin and turns OFF during a logic Low. With the
Negative Logic On/Off option, (no device code suffix, see
Ordering Information), the module turns OFF during logic High
and ON during logic Low. The On/Off signal is always
referenced to ground.
For positive logic modules, the circuit configuration for using
the On/Off pin is shown in Figure 32. When the external
transistor Q1 is in the OFF state, the ON/OFF pin is pulled high
and transistor Q2 is OFF leading to Q3 also being OFF which
turns the module ON. The external resistor Rpullup (100k
recommended) must be sized so that VON/OFF is never more
than 12V when Q1 is OFF. In particular, if Vpullup is made the
same as the input voltage Vin, the resistor Rpullup must be large
enough so that VON/OFF is never more than 12V. If the On/Off pin
is left floating the module will be in the ON state.
For negative logic On/Off modules, the circuit configuration is
shown in Fig. 33. When the external transistor Q1 is in the ON
state, the ON/OFF pin is pulled low causing transistor Q2 to be
OFF and the module to be turned ON. To turn the module OFF,
Q1 is turned OFF, causing the ON/OFF pin to be pulled high
turing Q2 ON and the module to be turned OFF. Leaving the
On/Off pin floating will leave the module in an OFF state.

logic.
Figure 33. Circuit configuration for using negative On/Off
logic.
Overcurrent Protection
To provide protection in a fault (output overload) condition, the
unit is equipped with internal current-limiting circuitry and can
endure current limiting continuously. At the point of
current-limit inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought back into
its specified range. The 9-36V ProLynx modules employ an
innovative, patent pending, ‘AutoLimit’ capability. This results in
automatic scaling of current limit with output voltage through
an inverse relationship of the current limit threshold with the
output voltage. This feature shown graphically in Fig. 34, allows
higher output currents to be drawn from the module at lower
output voltages thereby optimizing the power delivery
capability of the module.
Figure 34. Graph showing maximum output current
capability at different output voltages.
Over Temperature Protection
To provide protection in a fault condition, the unit is equipped
with a thermal shutdown circuit. The unit will shutdown if the
overtemperature threshold of 130oC is exceeded at the thermal
reference point Tref. The thermal shutdown is not intended as a
guarantee that the unit will survive temperatures beyond its
rating. Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.

Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the under voltage lockout
turn-on threshold.
Output Voltage Programming
The output voltage of the 9-36V ProLynxTM module can be
programmed to any voltage from 3Vdc to 18Vdc by connecting
a resistor between the Trim and GND pins of the module.
Certain restrictions apply on the output voltage set point
depending on the input voltage. These are shown in the Output
Voltage vs. Input Voltage Set Point Area plot in Fig. 9. Without
an external resistor between Trim and GND pins, the output of
the module will be 0.7Vdc. To calculate the value of the trim
resistor, Rtrim for a desired output voltage, use the following
equation:
( )
−
=k
Vo
Rtrim 7.0

Rtrim is the external resistor in kΩ, and Vo is the desired output
voltage.
Figure 35. Output Voltage vs. Input Voltage Set Point Area

different input voltages.
Table 1 provides Rtrim values required for some common
output voltages.

feature to minimize the effects of distribution losses by
regulating the voltage between the VS+ and Vo pin. The

Voltage Margining
Output voltage margining can be implemented in the 9-36V
ProLynxTM modules by connecting a resistor, Rmargin-up, from the
Trim pin to the ground pin for margining-up the output voltage
and by connecting a resistor, Rmargin-down, from the Trim pin to
output pin for margining-down. Figure 37 shows the circuit
configuration for output voltage margining. The Lynx
Programming Tool, available at www.gecriticalpower.com
under the Design Tools section, also calculates the values of
Rmargin-up and Rmargin-down for a specific output voltage and %

Tunable LoopTM
The 9-36V ProLynxTM modules have a new feature that
optimizes transient response of the module called Tunable
LoopTM.
External capacitors are usually added to the output of the
module for two reasons: to reduce output ripple and noise (see
Figures 30 and 31) and to reduce output voltage deviations
from the steady-state value in the presence of dynamic load
current changes. Adding external capacitance however affects
the voltage control loop of the module, typically causing the
loop to slow down with sluggish response. Larger values of
external capacitance could also cause the module to become
unstable.
The Tunable LoopTM allows the user to externally adjust the
voltage control loop to match the filter network connected to
the output of the module. The Tunable LoopTM is implemented
by connecting a series R-C between the VS+ and TRIM pins of
the module, as shown in Fig. 38. This R-C allows the user to
externally adjust the voltage loop feedback compensation of
the module.
Recommended values of RTUNE and CTUNE for different output
capacitor combinations are given in Tables 2, 3 and 4. Tables 2
and 3 show recommended values of RTUNE and CTUNE for
different values of ceramic output capacitors up to 100F that
might be needed for an application to meet output ripple and
noise requirements. Selecting RTUNE and CTUNE according to
Tables 2 and 3 will ensure stable operation of the module
In applications with tight output voltage limits in the presence
of dynamic current loading, additional output capacitance will
be required. Table 4 lists recommended values of RTUNE and
CTUNE in order to meet 2% output voltage deviation limits for
some common output voltages in the presence of a 50% of full
load step change with an input voltage of 12 or 28V.
Figure. 38. Circuit diagram showing connection of RTUME and
CTUNE to tune the control loop of the module.
Please contact your GE technical representative to obtain more
details of this feature as well as for guidelines on how to select
the right value of external R-C to tune the module for best
transient performance and stable operation for other output
capacitance values or input voltages other than 12V/28V.

Thermal Considerations
Power modules operate in a variety of thermal environments;
however, sufficient cooling should always be provided to help
ensure reliable operation.
Considerations include ambient temperature, airflow, module
power dissipation, and the need for increased reliability. A
reduction in the operating temperature of the module will
result in an increase in reliability. The thermal data presented
here is based on physical measurements taken in a wind
tunnel. The test set-up is shown in Figure 39. The preferred
airflow direction for the module is in Figure 40. The derating
data applies to airflow in either direction of the module’s short
axis.

Shock and Vibration
The APXW003 modules are designed to withstand elevated levels of shock and vibration to be able to operate in harsh
environments. The ruggedized modules have been successfully tested to the following conditions:
Non operating random vibration:
Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms
(Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes.
Operating shock to 40G per Mil Std. 810G, Method 516.4 Procedure I:
The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock
impulse characteristics as follows:
All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes.
Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of
40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen
shocks.
Operating vibration per Mil Std 810G, Method 514.5 Procedure I:
The APXW003 modules are designed and tested to vibration levels as outlined in MIL-STD-810G, Method 514.5, and Procedure 1,
using the Power Spectral Density (PSD) profiles as shown in Table 1 and Table 2 for all axes. Full compliance with performance
specifications was required during the performance test. No damage was allowed to the module and full compliance to
performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD-
810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and
endurance levels shown in Table 5 and Table 6 for all axes. The performance test has been split, with one half accomplished before
the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16
minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours
minimum per axis.

Surface Mount Information
Pick and Place
The 9-36V ProLynxTM modules use an open frame construction
and are designed for a fully automated assembly process. The
modules are fitted with a label designed to provide a large
surface area for pick and place operations. The label meets all
the requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow temperatures
of up to 300oC. The label also carries product information such
as product code, serial number and the location of
manufacture.
Nozzle Recommendations
The module weight has been kept to a minimum by using open
frame construction. Variables such as nozzle size, tip style,
vacuum pressure and placement speed should be considered
to optimize this process. The minimum recommended inside
nozzle diameter for reliable operation is 3mm. The maximum
nozzle outer diameter, which will safely fit within the allowable
component spacing, is 7 mm.
Bottom Side / First Side Assembly
This module is not recommended for assembly on the bottom
side of a customer board. If such an assembly is attempted,
components may fall off the module during the second reflow
process.
Lead Free Soldering
The 9-36V ProLynxTM modules are lead-free (Pb-free) and RoHS
compliant and fully compatible in a Pb-free soldering process.
Failure to observe the instructions below may result in the
failure of or cause damage to the modules and can adversely
affect long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for Nonhermetic Solid
State Surface Mount Devices) for both Pb-free solder profiles
and MSL classification procedures. This standard provides a
recommended forced-air-convection reflow profile based on
the volume and thickness of the package (table 4-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The
recommended linear reflow profile using Sn/Ag/Cu solder is
shown in Fig. 41. Soldering outside of the recommended profile
requires testing to verify results and performance.
For questions regarding Land grid array(LGA) soldering, solder
volume; please contact GE for special manufacturing process
instructions.
MSL Rating
The 9-36V ProLynxTM modules have a MSL rating of 2a.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages is
detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and
Use of Moisture/Reflow Sensitive Surface Mount Devices).
Moisture barrier bags (MBB) with desiccant are required
for MSL ratings of 2 or greater. These sealed packages
should not be broken until time of use. Once the original
package is broken, the floor life of the product at
conditions of 30°C and 60% relative humidity varies
according to the MSL rating (see J-STD-033A). The shelf
life for dry packed SMT packages will be a minimum of 12
months from the bag seal date, when stored at the
following conditions: < 40° C, < 90% relative humidity.

Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect both
the reliability of a power module and the testability of the
finished circuit-board assembly. For guidance on
appropriate soldering, cleaning and drying procedures,
refer to Board Mounted Power Modules: Soldering and
Cleaning Application Note (AN04-001).

Negative Output Operation
Basic Scheme
The 9-36V ProLynxTM modules can also be used to create
negative output voltages from a positive input voltage.
Changing the input connection to as shown in Figure 42
converts the module from a synchronous buck converter to a
synchronous flyback converter
Figure 44. Schematic Connection of 5A ProLynx module for
negative output applications.
Remote Enable
Figures 33 and 34 still apply for remote On/Off operation.
However the On/Off threshold is now with respect to –Vout
instead of Ground. Before the module turns on, output is zero
so GND and –Vout are at the same potential. After the modules
turns on, -Vout moves down and so will the ON/OFF threshold.
The following level shifting circuit can be used in applications
to limit exposure of the negative output voltage to the On/Off
circuitry.
Figure 45. On/Off Level Shifting Circuit for the 3A ProLynx
module for negative output applications.
Instead of directly turning Q1 On, the level shifting circuit is
used to turn Q1 On by first turning Q2 ON. When Q1 is in the
ON state, the ON/OFF pin is pulled low causing transistor Q5 to
be OFF and the module to be turned ON. Both Q1 and Q2 are
external transistors. To turn the module OFF, Q2 is turned OFF,
which turns Q1 OFF causing the ON/OFF pin to be pulled high
turning Q5 ON and the module to be turned OFF. If the On/Off
pin is left floating, the module will be in the OFF state.
Input Voltage Range
The 9-36V ProLynxTM modules when connected in a negative
output application will support a maximum input voltage
which is also a function of the output voltage. The sum of the
applied input voltage and magnitude of the output voltage
cannot exceed 36V. Vin(applied) +|Vout| ≤ 36 and Vout≤-3V. For
e.g. with a -12V output system the max input voltage that can
applied is only 24V. However, Figure 35 showing variation of
output voltage with Input Voltage should still be considered for
determining the required minimum input voltage.
Input voltage turn-on threshold remains the same as the
positive output connection. However the input turn-off
threshold tracks the output voltage and is reduced by the
same level. The listed input Turn-Off threshold of 7.35V when
applied to a -3.3Vout application will be measured as a 4.05V
(7.35V – 3.3V) threshold. Operating at input voltages below 9V
may cause the module to shut down earlier due to OCP
inception
Output Voltage Range
The 9-36V ProLynxTM modules will support the values of trim
resistors indicated in Table 1 to generate the same output
voltage, except with sign inversion
Overcurrent Protection
The 9-36V ProLynx modules will automatic scale current limit
with output voltage through an inverse relationship of the
current limit threshold even in negative output voltage mode.
This feature is shown graphically in Fig. 34, allows higher
output currents to be drawn from the module at lower output
voltages thereby optimizing the power delivery capability of
the module.

capability at different output voltages.
