Description
The 12V Austin LynxTM Programmable SIP 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 ranging from 0.75Vdc to 5.5Vdc, programmable via an external resistor over a wide range of input
voltage (VIN = 10 – 14Vdc). Their open-frame construction and small footprint enable designers to develop cost-
and space-efficient solutions. Standard features include remote On/Off, remote sense, output voltage adjustment,
overcurrent and overtemperature protection.

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.

Design Considerations (continued)
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 12V Austin Lynx Programmable 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.

125oC (typical), but the thermal shutdown is not
intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will
automatically restarts after it cools down.
The 12V Austin Lynx Programmable SIP power
modules feature an On/Off pin for remote On/Off
operation. If not using the remote On/Off pin, leave the
pin open (module will be On). The On/Off pin signal
(Von/Off) is referenced to ground. To switch the module
on and off using remote On/Off, connect an open
collector npn transistor between the On/Off pin and the
ground pin (See Figure 27).
During a logic-high (On/Off pin is pulled high internal to
the module) when the transistor is in the Off state, the
power module is ON. The maximum allowable leakage
current of the transistor when Von/off = VIN,max is 10µA.
During a logic-low when the transistor is turned-on, the
power module is OFF. During this state VOn/Off is less
than 0.3V and the maximum IOn/Off = 1mA.

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 3A.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.

tolerance of ±2% is achieved as specified in the
electrical specification. The POL Programming Tool,
available at www.lineagepower.com under the Design
Tools section, helps determine the required external
trim resistor needed for a specific output voltage.
Output Voltage Programming
The output voltage of the 12V Austin Lynx
Programmable SIP module can be programmed to any
voltage from 0.75 Vdc to 5.5 Vdc by connecting a single
resistor (shown as Rtrim in Figure 28) 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:
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 margining can be implemented in the
12V Austin Lynx Programmable SIP 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 29 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 Lineage Power technical representative for
additional details.

Austin Lynx Programmable SIP module to 1.8 Vdc,

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

power. When the Remote Sense feature is not being

Thermal Considerations
The power modules operate in a variety of thermal
environments; however, sufficient cooling should always
be provided to help ensure reliable operation.

(1.0)
Wind Tunnel
PWBs
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 32. Note that the airflow is parallel to
the long axis of the module as shown in figure 31. The
derating data applies to airflow in either direction of the
module’s long axis.

showing the maximum output current that can be
delivered at different local ambient temperature (TA) for
airflow conditions ranging from natural convection and
up to 2m/s (400 ft./min) are shown in the Characteristics
Curves section.
The thermal reference point, Tref used in the
specifications is shown in Figure 31. For reliable
operation this temperature should not exceed 115 oC.
The output power of the module should not exceed the
rated power of the module (Vo,set x Io,max).

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.
