Description

The Pico TLynxTM 3A power modules are non-isolated dc-dc converters that can deliver up to 3A of output current. These

modules operate over a wide range of input voltage (VIN = 2.4Vdc-5.5Vdc) and provide a precisely regulated output voltage

from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage,

over current and overtemperature protection, and output voltage sequencing (APTH versions). A new feature, 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.

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 5A (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 Pico TLynxTM 3A 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, low-ESR ceramic capacitors

are recommended at the input of the module. Figure 34 shows

the input ripple voltage for various output voltages at 3A of

load current with 1x22 µF or 2x22 µF ceramic capacitors and

an input of 5V. Figure 35 shows data for the 3.3Vin case, with

1x22µF or 2x22µF of ceramic capacitors at the input.

Output Filtering

The Pico TLynxTM 3A 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 ceramic and polymer

capacitors are recommended to improve the dynamic

response of the module. Figure 36 provides output ripple

information for different external capacitance values at

various Vo and for load currents of 3A while maintaining an

input voltage of 5V. Fig 37 shows the performance with a

3.3V input. 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 Loop 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, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12

(EN60950-1) Licensed.

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 5A in the positive input lead.

Feature Descriptions

Remote On/Off

The Pico TLynxTM 3A 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 either On/Off logic option, leaving

the On/Off pin disconnected will turn the module ON when

input voltage is present.

For positive logic modules, the circuit configuration for using

the On/Off pin is shown in Figure 38. When the external

transistor Q1 is in the OFF state, Q2 is ON, the internal PWM

Enable signal is pulled low and the module is ON. When

transistor Q1 is turned ON, the On/Off pin is pulled low, Q2 is

turned off and the internal PWM Enable signal is pulled high

through the 100K internal pull-up resistor and the module is

OFF.

Figure 38. Circuit configuration for using positive On/Off

logic.

For negative logic On/Off modules, the circuit configuration is

shown in Fig. 39. The On/Off pin should be pulled high with

an external pull-up resistor (suggested value for the 2.4V to

5.5Vin range is 3.6Kohms). When transistor Q1 is in the OFF

state, the On/Off pin is pulled high and the module is OFF.

The On/Off threshold for logic High on the On/Off pin

depends on the input voltage and its minimum value is VIN –

1.6V. To turn the module ON, Q1 is turned ON pulling the

On/Off pin low.

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.

Overtemperature 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 140oC 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 undervoltage lockout

turn-on threshold.

Output Voltage Programming

The output voltage of the Pico TLynxTM 3A modules can be

programmed to any voltage from 0.6Vdc to 3.63Vdc 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. 40.

The Upper Limit curve shows that the entire output voltage

range is available with the maximum input voltage of 5.5V. The

Lower Limit curve shows that for output voltages of 1.8V and

higher, the input voltage needs to be larger than the minimum

of 2.4V.

Remote Sense

The Pico TLynxTM 3A modules have a Remote Sense feature

to minimize the effects of distribution losses by regulating

the voltage at the SENSE pin. The voltage between the

SENSE pin and VOUT pin must not exceed 0.5V. Note that the

output voltage of the module cannot exceed the specified

maximum value. This includes the voltage drop between the

SENSE and Vout pins. When the Remote Sense feature is not

being used, connect the SENSE pin to the VOUT pin.

Voltage Margining

Output voltage margining can be implemented in the Pico

TLynxTM 3A 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 42 shows

the circuit configuration for output voltage margining. The

POL Programming Tool, available at www.lineagepower.com

under the Design Tools section, also calculates the values of

Rmargin-up and Rmargin-down for a specific output voltage and %

margin. Please consult your local GE technical

representative for additional details.

Monotonic Start-up and Shutdown

The Pico TLynxTM 3A modules have monotonic start-up and

shutdown behavior for any combination of rated input voltage,

output current and operating temperature range.

Startup into Pre-biased Output

The 5.5V Pico TLynxTM 6A modules can start into a prebiased

output as long as the prebias voltage is 0.5V less than the set

output voltage. Note that prebias operation is not supported

when output voltage sequencing is used.

Output Voltage Sequencing

The Pico TLynxTM modules include a sequencing feature, EZ-

SEQUENCE that enables users to implement various types of

output voltage sequencing in their applications. This is

accomplished via an additional sequencing pin. When not

using the sequencing feature, either tie the SEQ pin to VIN or

leave it unconnected.

When an analog voltage is applied to the SEQ pin, the output

voltage tracks this voltage until the output reaches the set-

point voltage. The final value of the SEQ voltage must be set

higher than the set-point voltage of the module. The output

voltage follows the voltage on the SEQ pin on a one-to-one

volt basis. By connecting the SEQ pins of multiple modules

together, all modules can track their output voltages to the

voltage applied on the SEQ pin.

For proper voltage sequencing, first, input voltage is applied to

the module. The On/Off pin of the module is left unconnected

(or tied to GND for negative logic modules or tied to VIN for

positive logic modules) so that the module is ON by default.

After applying input voltage to the module, a minimum

10msec delay is required before applying voltage on the SEQ

pin. This delay gives the module enough time to complete its

internal power-up soft-start cycle. During the delay time, the

SEQ pin should be held close to ground (nominally 50mV ± 20

mV). This is required to keep the internal op-amp out of

Figure 43. Circuit showing connection of the sequencing

signal to the SEQ pin.

After the 10msec delay, an analog voltage is applied to the

SEQ pin and the output voltage of the module will track this

voltage on a one-to-one volt bases until the output reaches

the set-point voltage. To initiate simultaneous shutdown of

the modules, the SEQ pin voltage is lowered in a controlled

manner. The output voltage of the modules tracks the

voltages below their set-point voltages on a one-to-one

basis. A valid input voltage must be maintained until the

tracking and output voltages reach ground potential.

When using the EZ-SEQUENCETM feature to control start-up

of the module, pre-bias immunity during start-up is disabled.

The pre-bias immunity feature of the module relies on the

module being in the diode-mode during start-up. When

using the EZ-SEQUENCETM feature, modules goes through an

internal set-up time of 10msec, and will be in synchronous

rectification mode when the voltage at the SEQ pin is applied.

This will result in the module sinking current if a pre-bias

voltage is present at the output of the module. When pre-

bias immunity during start-up is required, the EZ-

SEQUENCETM feature must be disabled. For additional

guidelines on using the EZ-SEQUENCETM feature please refer

to Application Note AN04-008 “Application Guidelines for

Non-Isolated Converters: Guidelines for Sequencing of

Multiple Modules”, or contact the GE technical representative

for additional information.

Tunable Loop

The 5V Pico TLynxTM 3A 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 36 and 37) 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 Loop is implemented

by connecting a series R-C between the SENSE and TRIM pins

of the module, as shown in Fig. 44. This R-C allows the user to

externally adjust the voltage loop feedback compensation of

the module.

Figure. 44. Circuit diagram showing connection of RTUME

and CTUNE to tune the control loop of the module.

Recommended values of RTUNE and CTUNE for different output

capacitor combinations are given in Tables 2, 3, 4 and 5.

Tables 2 and 4 show the recommended values of RTUNE and

CTUNE for different values of ceramic output capacitors up to

470uF that might be needed for an application to meet

output ripple and noise requirements for 5Vin and 3.3Vin

respectively. Selecting RTUNE and CTUNE according to Table 2

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. Tables 3 and 5 list 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

1.5A to 3A step change (50% of full load), with an input

voltage of 5Vin and 3.3Vin respectively

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 3.3 or

5V.

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 45. The preferred

airflow direction for the module is shown in Figure 46.

Shock and Vibration

The ruggedized (-D version) of the 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. 810F, 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 810F, Method 514.5 Procedure I:

The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F, Method 514.5, and

Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 6 and Table 7 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 6 and Table 7 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 Pico TLynxTM 3A 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. If assembly on the bottom side is planned, please

contact GE for special manufacturing process instructions.

Only ruggedized (-D version) modules with additional epoxy will

work with a customer’s first side assembly. For other versions,

first side assembly should be avoided

Lead Free Soldering

The Pico TLynxTM 3A 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. 47.

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 Pico TLynxTM 3A 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.

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,
