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 fastacting 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.

very low ESR ceramic capacitors are recommended at
the input of the module. Figure 26 shows input ripple

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.
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.
LINEAGE POWER
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 fastacting fuse with a maximum rating of 6A in the positive
input lead.

Feature Description
Remote On/Off
TM
The Austin SuperLynx 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).
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.

Output Voltage Programming
TM
The output voltage of the Austin SuperLynx 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:

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.
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

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:
Vtrim = (0.7 − 0.0667 × {Vo − 0.7525})
For example, to program the output voltage of a
SuperLynxTM module to 3.3 Vdc, Vtrim is calculated as
follows:
Vtrim = (0.7 − 0.0667 × {3.3 − 0.7525})
Vtrim = 0.530V

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).

Voltage Margining
Output voltage margining can be implemented in the

Austin SuperLynx 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

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

Wind Tunnel
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.

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).
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame BoardMounted Power Modules” for a detailed discussion of
thermal aspects including maximum device temperatures.

Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves
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

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 RoHScompliant 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.
