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 20A,
fast-acting, glass type fuse rated for 32V (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
Input Filtering
Austin SuperLynxTM SIP 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, low-ESR polymer and
ceramic capacitors are recommended at the input of the
module. Figure 26 shows input ripple voltage (mVp-p)
for various outputs with 1x150 µF polymer capacitors
(Panasonic p/n: EEFUE0J151R, Sanyo p/n:
6TPE150M) in parallel with 1 x 47 µF ceramic capacitor
(Panasonic p/n: ECJ-5YB0J476M, Taiyo- Yuden p/n:

Design Considerations (continued)
Output Filtering
The Austin SuperLynxTM 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.
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.

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.
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 20A in the positive
input lead

SIP Non-isolated Power Modules:
Feature Description
Remote On/Off
The Austin SuperLynxTM SIP power modules feature an
On/Off pin for remote On/Off operation. The On/Off pin
is pulled high with an external pull-up resistor (typical
Rpull-up = 68k, ± 5%) as shown in Fig. 28. 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 1.5Vdc. 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.

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 3.5A.
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 T
exceeds 125
not intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will

Output Voltage Programming
The output voltage of the Austin SuperLynxTM SIP can
be programmed to any voltage from 0.75 Vdc to 3.63
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:

Remote Sense
The Austin SuperLynxTM 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 32). 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 the output pin
of the module.

Thermal Considerations
The 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 Fig. 33. Note that the airflow is parallel to
the long axis of the module as shown in Fig. 34. The
derating data applies to airflow in either direction of the
module’s long axis.

The thermal reference point, T
specifications is shown in Figure 33. For reliable
operation this temperature should not exceed 115
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.

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.
