Description
Austin SuperLynxTM 12V SIP power modules are non-isolated dc-dc converters that can deliver up to 16A of output
current with full load efficiency of 92% 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 fast-
acting fuse with a maximum rating of 15 A (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, 6x47 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 further minimize ripple voltage at the input,
very low ESR ceramic capacitors are recommended at
the input of the module. Figure 26 shows input ripple

Design Considerations (continued)
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.
Output Filtering
The Austin SuperLynxTM 12V 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 6A 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.

temperatures beyond its rating. The module will
automatically restarts after it cools down.
Feature Description
Remote On/Off
The Austin SuperLynxTM 12V SIP power modules feature
an On/Off pin for remote On/Off operation of the module.
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 or N-channel FET between the On/Off pin and
the ground pin (See Figure 27).
Output Voltage Programming
The output voltage of the Austin SuperLynxTM 12V can
be programmed to any voltage from 0.75Vdc to 5.5Vdc
by connecting a resistor (shown as Rtrim in Figure 28)
between the Trim and GND pins of the module.
Without an external resistor between the Trim and
GND pins, the output of the module will be 0.7525Vdc.
To calculate the value of the trim resistor, Rtrim for a
desired output voltage, use the following equation:
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.

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.

voltage using an external resistor.
Austin SuperLynxTM 12Vdc can also be programmed by
applying a voltage between the TRIM and GND pins
(Figure 29). The following equation can be used to
determine the value of Vtrim needed to obtain a desired
output voltage Vo:
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.

For example, to program the output voltage of a
SuperLynxTM module to 3.3 Vdc, Vtrim is calculated as
follows:
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the thermal reference point Tref, exceeds
125oC (typical), but the thermal shutdown is not

as the voltage at the output terminals multiplied by the

voltage of the module can be increased, which at the
same output current would increase the power output of

Voltage Margining
LOAD
Output voltage margining can be implemented in the
Austin SuperLynxTM 12V 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 30 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.

Remote Sense
The Austin SuperLynxTM 12V SIP 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.

Thermal Considerations
25.4_
Wind Tunnel
PWBs
(1.0)
Power modules operate in a variety of thermal
environments; however, sufficient cooling should always
be provided to help ensure reliable operation.
Powe r Mod ule
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.

The thermal reference point, Tref used in the
specifications is shown in Figure 32. For reliable
operation this temperature should not exceed 115oC.
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.
