Description
TM
The 12V Pico TLynx 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
TM
shock and vibration. A new feature, the Tunable Loop , 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.

As
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.

The 12V Pico TLynx 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

The 12V Pico TLynx 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

Feature Descriptions
Remote Enable
TM
The 12V Pico TLynx 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.

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.

For the converter output to be considered meeting

the input must meet SELV requirements. The power
module has extra-low voltage (ELV) outputs when all

The input to these units is to be provided with a fastacting fuse with a maximum rating of 6A in the
positive input lead.

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.

Without an external resistor between Trim and GND

desired output voltage, use the following equation:

Rtrim is the external resistor in kΩ
Vo is the desired output voltage.
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
TM
The output voltage of the 12V Pico TLynx 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.

Remote Sense
TM
The 12V Pico TLynx 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

Startup into Pre-biased Output
TM
The 12V Pico TLynx 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
TM
The 12V Pico TLynx 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
R1 =
24950
ohms,
V IN − 0.05
the voltage at the sequencing pin will be 50mV when
the sequencing signal is at zero.

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

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.
TM
When using the EZ-SEQUENCE feature to control
start-up of the module, pre-bias immunity during startup is disabled. The pre-bias immunity feature of the
module relies on the module being in the diode-mode
TM
during start-up. When using the EZ-SEQUENCE
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 EZTM
SEQUENCE 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 Lineage Power technical representative for
additional information.
The 12V Pico TLynx 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
TM
The 12V Pico TLynx 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.
TM
The Tunable Loop 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.

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

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

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.

Surface Mount Information
Pick and Place
The 12V Pico TLynxTM 6A 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
o
temperatures of up to 300 C. 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 (Pbfree) and RoHS compliant and fully compatible in a Pbfree soldering process. Failure to observe the
instructions below may result in the failure of or cause
damage to the modules and can adversely affect longterm 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.
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).
MSL Rating
The 12V Pico TLynxTM 6A modules have a MSL rating
of 2.
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
