Description
The 12V Pico TLynxTM 6A power modules are non-isolated dc-dc converters that can deliver up to 6A of output current. These
modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output voltage from
0.59Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over
current and over temperature protection, and output voltage sequencing (APTS versions). The Ruggedized version (-D) is capable
of operation up to 105°C and withstand high levels of shock and vibration. 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 6A (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 Pico TLynxTM 6A 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 6A of load current with 1x10 µF or 1x22 µF ceramic
capacitors and an input of 12V.

Output Filtering
The 12V Pico TLynxTM 6A 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. Figure 41 provides output ripple
information for different external capacitance values at
various Vo and for a load current of 6A. 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, 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 6A in the positive input lead.
Feature Descriptions
Remote Enable
The 12V Pico TLynxTM 6A power 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 42. When the external
transistor Q1 is in the OFF state, the internal PWM Enable
signal is pulled high through an internal 1.5MΩ resistor and
the external pullup resistor and the module is ON. When
transistor Q1 is turned ON, the On/Off pin is pulled low and
the module is OFF. A suggested value for Rpullup is 20kΩ.

For negative logic On/Off modules, the circuit configuration
is shown in Fig. 43. The On/Off pin should be pulled high with
an external pull-up resistor (suggested value for the 4.5V to
14V input range is 20Kohms). When transistor Q2 is in the
OFF state, the On/Off pin is pulled high, transistor Q1 is
turned ON and the module is OFF. To turn the module ON,
Q2 is turned ON pulling the On/Off pin low, turning transistor
Q1 OFF resulting in the PWM Enable pin going high.

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 Pico TLynxTM 6A modules can be
programmed to any voltage from 0.59dc 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 Upper Limit curve shows that for output voltages of 0.9V
and lower, the input voltage must be lower than the maximum
of 14V. The Lower Limit curve shows that for output voltages of
3.8V and higher, the input voltage needs to be larger than the
minimum of 4.5V.

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 Pico TLynxTM 6A 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 Pico
TLynxTM 6A 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
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.

Monotonic Start-up and Shutdown
The 12V Pico TLynxTM 6A 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 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 12V Pico TLynxTM 6A 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 basis. By connecting
multiple modules together, multiple 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
saturation thus preventing output overshoot during the
start of the sequencing ramp. By selecting resistor R1
(see fig. 47) according to the following equation

the voltage at the sequencing pin will be 50mV when the

Figure 47. Circuit showing connection of the sequencing

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.
Power Good
The 12V Pico TLynxTM 6A 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 ±10% 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 Pico TLynxTM 6A 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. 41) 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. 48. 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 and 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. Table 3 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 3A to 6A step
change (50% of full load), with an input voltage of 12V.
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.

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 49. The preferred airflow direction
for the module is in Figure 50.

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 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 4 and Table 5 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.

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.
Lead Free Soldering
The 12V Pico TLynxTM 6A 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. 51.
Soldering outside of the recommended profile requires testing to
verify results and performance.
MSL Rating
The 12V Pico TLynxTM 6A 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).
