Description
The 12V Micro TLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 12A 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 0.69Vdc to 5.5Vdc, programmable via an external resistor. The new
Ruggedized version (-D) is capable of operation up to 105°C and can withstand high levels of shock and vibration.
Features include frequency synchronization, remote On/Off, adjustable output voltage, over current and
overtemperature protection, power good and output voltage sequencing. 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 15A (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.

Input Filtering
The 12V Micro TLynxTM 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 1x22 µF or 2x22
µF ceramic capacitors and an input of 12V.

The 12V Micro TLynxTM 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 full load
currents of 12A. 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

Feature Descriptions
VIN+
MODULE
Remote Enable
The 12V Micro TLynxTM 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
24.9kΩ 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 Q1 is in the OFF state, the
On/Off pin is pulled high, internal transistor Q2 is turned
ON and the module is OFF. To turn the module ON, Q1
is turned ON pulling the On/Off pin low, turning
transistor Q2 OFF resulting in the PWM Enable pin
going high and the module turning ON.
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.

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 133oC 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 Micro TLynxTM module
can be programmed to any voltage from 0.69dc 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 3.3V and higher, the input voltage
needs to be larger than the minimum of 4.5V.
Without an external resistor between Trim and GND
pins, the output of the module will be 0.69Vdc. To
calculate the value of the trim resistor, Rtrim for a
desired output voltage, use the following equation:
⎡
⎤
6.9
Rtrim = ⎢
⎥ kΩ
⎣ (Vo − 0.69 ) ⎦
Rtrim is the external resistor in kΩ, and Vo is the desired
output voltage.

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 Micro TLynxTM power modules have a Remote
Sense feature to minimize the effects of distribution
losses by regulating the voltage between the VS+ and
VS– pins. The voltage between the VS– and GND pins
of the module must not drop below –0.2V. If Remote
Sense is being used, the voltage between VS+ and VS–
cannot be more than 0.5V larger than the voltage
between VOUT and GND. Note that the output voltage
of the module cannot exceed the specified maximum
value. When the Remote Sense feature is not being
used, connect the VS+ pin to the VOUT pin and the VS–
pin to the GND pin.
Monotonic Start-up and Shutdown
The 12V Micro TLynxTM modules have monotonic startup and shutdown behavior for any combination of rated
input voltage, output current and operating temperature
range.
LINEAGE POWER
Figure 45. Circuit configuration for programming
output voltage using an external resistor.
Startup into Pre-biased Output
The 12V Micro TLynxTM 12A 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.
Voltage Margining
Output voltage margining can be implemented in the
TM
12V Micro TLynx 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 Lynx
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 Lineage
Power technical representative for additional details.
Output Voltage Sequencing
The 12V Micro 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 multiple modules together, multiple modules
can track their output voltages to the voltage applied on
the SEQ pin.

Output voltage
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.
During this time, a voltage of 50mV (± 20 mV) is
maintained on the SEQ pin.
This can be done by applying the sequencing voltage
through a resistor R1connected in series with 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
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.
LINEAGE POWER

Figure 47. Circuit showing connection of the
sequencing signal to the SEQ pin.
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 EZSEQUENCETM feature must be disabled. For

feature please refer to Application Note AN04-008

contact the Lineage Power technical representative for
additional information.
Power Good
TM
The 12V MIcro TLynx 12A 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 ±11% outside the setpoint value. The
PGOOD terminal should be connected through a pullup
resistor (suggested value 100KΩ) to a source of 6VDC
or less.
Synchronization
The 12V Micro TLynxTM series of modules can be
synchronized using an external signal. Details of the
SYNC signal are provided in the Electrical
Specifications table. If the synchronization function is
not being used, leave the SYNC pin floating.

Tunable LoopTM
TM
The 12V Micro TLynx 12A modules have a new
feature that optimizes transient response of the module
TM
called Tunable Loop .
External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple and
noise (see Figure 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.

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 1 and Table 2 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

Surface Mount Information
Pick and Place
The 12V Micro TLynxTM 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.
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.
300
Per J-STD-020 Rev. C
Peak Temp 260°C
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 Micro TLynxTM 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.

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 Micro TLynxTM 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,
