Description
Austin LynxTM II 12V SIP (singe in-line package) power modules are non-isolated dc-dc converters that can deliver
up to 10A of output current with full load efficiency of 93% at 3.3V output. These modules provide a precisely
regulated output voltage programmable via an external resistor from 0.75Vdc to 5.0Vdc over a wide range of input
voltage (VIN = 8.3 – 14Vdc). The Austin LynxTM II 12V series has a sequencing feature, EZ-SEQUENCETM that
enable designers to implement various types of output voltage sequencing when powering multiple voltages on a
board.

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 being
part of a complex 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 15A,
time-delay fuse (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.

In a typical application, 4x47 µF low-ESR tantalum
capacitors (AVX part #: TPSE476M025R0100, 47µF
25V 100 mΩ ESR tantalum capacitor) will be sufficient
to provide adequate ripple voltage at the input of the
module. To minimize ripple voltage at the input, low
ESR ceramic capacitors are recommended at the input
of the module. Figure 26 shows input ripple voltage

Safety Considerations
Output Filtering
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.
The Austin LynxTM II SIP module is designed for low
output ripple voltage and will meet the maximum output
ripple specification with 1 µF ceramic and 10 µF
tantalum 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.
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 15A in the positive
input lead.
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. For stable operation
of the module, limit the capacitance to less than the
maximum output capacitance as specified in the
electrical specification table.

The Austin LynxTM II SMT power modules feature an
On/Off pin for remote On/Off operation. Two On/Off
logic options are available in the Austin LynxTM II series
modules. Positive Logic On/Off signal, device code
suffix “4”, turns the module ON during a logic High on
the On/Off pin and turns the module OFF during a logic
Low. Negative logic On/Off signal, no device code
suffix, turns the module OFF during logic High on the
On/Off pin and turns the module ON during logic Low.

For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 27. The On/Off
pin is an open collector/drain logic input signal (Von/Off)
that is referenced to ground. During a logic-high (On/Off
pin is pulled high internal to the module) when the
transistor Q1 is in the Off state, the power module is
ON. Maximum allowable leakage current of the
transistor when Von/off = VIN,max is 10µA. Applying a
logic-low when the transistor Q1 is turned-On, the power
module is OFF. During this state VOn/Off must be less
than 0.3V. When not using positive logic On/off pin,
leave the pin unconnected or tie to VIN.

logic On/OFF.
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. The typical average output current during hiccup
is 3.0A.

For negative logic On/Off devices, the circuit
configuration is shown is Figure 28. The On/Off pin is
pulled high with an external pull-up resistor (typical Rpull-
up = 68k, +/- 5%). When transistor Q1 is in the Off state,
logic High is applied to the On/Off pin and the power
module is Off. The minimum On/off voltage for logic
High on the On/Off pin is 2.5Vdc. To turn the module
ON, logic Low is applied to the On/Off pin by turning ON
Q1. When not using the negative logic On/Off, leave
the pin unconnected or tie to GND.

Tools section, helps determine the required external trim
resistor needed for a specific output voltage.
Feature Descriptions (continued)
The amount of power delivered by the module is defined
as the voltage at the output terminals multiplied by the
output current. When using the trim feature, the output
voltage of the module can be increased, which at the
same output current would increase the power output of
the module. Care should be taken to ensure that the
maximum output power of the module remains at or
below the maximum rated power (Pmax = Vo,set x Io,max).
Output Voltage Programming
The output voltage of the Austin LynxTM II SMT can be
programmed to any voltage from 0.75 Vdc to 5.5 Vdc by
connecting a single resistor (shown as Rtrim in Figure
29) between the TRIM and GND pins of the module.
Without an external resistor between the TRIM pin and
the ground, the output voltage of the module is 0.7525
Vdc. To calculate the value of the resistor Rtrim for a
particular output voltage Vo, use the following equation:
Voltage Margining
Output voltage margining can be implemented in the
Austin LynxTM II 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 the Output pin
for margining-down. Figure 30 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

Voltage Sequencing
Remote Sense
The Austin LynxTM II series of modules include a
sequencing feature, EZ-SEQUENCETM 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.
The Austin LynxTM II SMT power modules have a
Remote Sense feature to minimize the effects of
distribution losses by regulating the voltage at the
Remote Sense pin (See Figure 31). The voltage
between the Sense pin and Vo pin must not exceed
0.5V.
The amount of power delivered by the module is defined
as the output voltage multiplied by the output current
(Vo x Io). When using Remote Sense, the output
voltage of the module can increase, which if the same
output is maintained, increases the power output by the
module. Make sure that the maximum output power of
the module remains at or below the maximum rated
power. When the Remote Sense feature is not being
used, connect the Remote Sense pin to output pin of the
module.
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 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, customers can get multiple modules
to 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 of 10msec delay is
required before applying voltage on the SEQ pin.
During this time, potential of 50mV (± 10 mV) is

maintained on the SEQ pin. After 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 output reaches the set-point
voltage. To initiate simultaneous shutdown of the
modules, the SEQ pin voltage is lowered in a controlled
manner. 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.
Figure 31. Remote sense circuit configuration.
When using the EZ-SEQUENCETM feature to control
start-up of the module, pre-bias immunity feature 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 voltage at the
SEQ pin is applied. This will result in sinking current in
the module if 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

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 33. Note that the airflow is parallel to
the long axis of the module as shown in figure 32. The
derating data applies to airflow in either direction of the
module’s long axis.

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.
Through-Hole Lead-Free Soldering
Information
The RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-compliant finish that is compatible
with both Pb and Pb-free wave soldering processes. A
maximum preheat rate of 3°C/s is suggested. The wave
preheat process should be such that the temperature of
the power module board is kept below 210°C. For Pb
solder, the recommended pot temperature is 260°C,
while the Pb-free solder pot is 270°C max. Not all
RoHS-compliant through-hole products can be
processed with paste-through-hole Pb or Pb-free reflow
process. If additional information is needed, please
consult with your Lineage Power technical
representative for more details.
