Description
The 12V PicoTLynxTM 2A power modules are non-isolated dc-dc converters that can deliver up to 2A of output current. These
modules operate over a wide range of input voltage (VIN = 3Vdc-14Vdc) and provide a precisely regulated output voltage from
0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current
and over temperature protection. 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 4A (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 12V PicoTLynxTM 2A 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
40 shows the input ripple voltage for various output
voltages at 2A of load current with 1x10 µF or 1x22 µF
ceramic capacitors and an input of 5V. Figure 41
shows the input ripple voltage for an input of 12V

Output Filtering
The 12V PicoTLynxTM 2A modules are designed for low
output ripple voltage and will meet the maximum output
ripple specification with 0.1 µF ceramic and 22µF 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.
A minimum 22uF External Cap must be used. Figure 42 provides
output ripple information for different external capacitance
values at various Vo and for a load current of 2A. For stable
operation of the module, limit the capacitance to less than the

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, and DIN EN 60950-1 (VDE 0805 Teil 1):2006-
11
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 4A in the positive input lead.
Feature Descriptions
Remote Enable
The 12V PicoTLynxTM 2A power modules feature an
On/Off pin for remote On/Off operation. 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. Leaving the On/Off pin
disconnected will turn the module ON when input voltage
is present.
The circuit configuration is shown in Fig. 43.

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 12V PicoTLynxTM 2A modules can be
programmed to any voltage from 0.6dc to 5.5Vdc 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. 44. The
Lower Limit curve shows that for output voltages of 2.4V and
higher, the input voltage needs to be larger than the minimum
of 3V.

By using a ±0.5% tolerance trim resistor with a TC of ±100ppm,
a set point tolerance of ±1.5% can be achieved as specified in
the electrical specification.
Remote Sense
The 12V PicoTLynxTM 2A power 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
12V PicoTLynxTM 2A 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 46 shows the circuit
configuration for output voltage margining. The POL

Monotonic Start-up and Shutdown
The 12V PicoTLynxTM 2A 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 12V PicoTLynxTM 2A modules can start into a prebiased
output as long as the prebias voltage is 0.5V less than the set
output voltage.
Power Good
The 12V PicoTLynxTM 2A modules provide a Power Good
(PGOOD) signal that is implemented with an open-drain output
to indicate that the output voltage is within the regulation limits
of the power module. The PGOOD signal will be de-asserted to
a low state if any condition such as overtemperature,
overcurrent or loss of regulation occurs that would result in the
output voltage going ±12.5% outside the setpoint value. The
PGOOD terminal should be connected through a pullup resistor
(suggested value 100KΩ) to a source of 5VDC or lower.
Tunable LoopTM
The 12V PicoTLynxTM 2A 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
Fig. 52) 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 SENSE and TRIM pins of
the module, as shown in Fig. 47. 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

3. Table 2 shows 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. 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, 4 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 1A to 2A step change
(50% of full load), for input voltages of 12V, 5V and 3.3V
respectively.
Please contact your GE Critical Power 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.

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 48. The preferred airflow direction
for the module is in Figure 49.

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 12V PicoTLynxTM 2A 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 Critical Power 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 12V PicoTLynxTM 2A 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). A 6 mil thick stencil is
recommended.
For questions regarding Land grid array(LGA) soldering, solder
volume; please contact GE Critical Power for special
manufacturing process instructions.
The recommended linear reflow profile using Sn/Ag/Cu solder is
shown in Fig. 50. Soldering outside of the recommended profile
requires testing to verify results and performance.
MSL Rating
The 12V PicoTLynxTM 2A 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).
