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.

Design Considerations

Input Filtering

The Austin SuperLynxTM 12V SMT module should be connected
to a low-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.

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 voltage (mVp-p) for various outputs with 6x47 µF
tantalum capacitors and with 6x22 µF ceramic capacitor (TDK
part #: C4532X5R1C226M) at full load. .

10Vdc –14Vdc input; 0.75Vdc to 5.5Vdc output; 16A Output Current

Design Considerations (continued)

Output Filtering

The Austin SuperLynxTM 12V SMT 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.

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.

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

12V Austin SuperLynxTM 16A: Non-Isolated DC-DC Power Modules

10Vdc –14Vdc input; 0.75Vdc to 5.5Vdc output; 16A Output Current

Feature Description

Remote On/Off

The Austin SuperLynxTM 12V SMT 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 between the On/Off pin and GND
(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 = V
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.

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
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.

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:

Rtrim

Rtrim is the external resistor in Ω

Vo is the desired output voltage

For example, to program the output voltage of the Austin

By using a 1% tolerance trim resistor, set point 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.

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 (P

).

Remote Sense

The Austin SuperLynxTM 12V 12V SMTpower 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

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 short axis of the module as shown in figure 32.
The derating data applies to airflow in either direction of the
module’s short axis.

Surface Mount Information

Pick and Place

The Austin SuperLynxTM 12V SMT modules use an open
frame construction and are designed for a fully automated
assembly process. The modules are fitted with a label
designed to provide a large surface area for pick and place
operations. The label meets all the requirements for surface
mount processing, as well as safety standards, and is able to
withstand reflow temperatures of up to 300
also carries product information such as product code, serial
number and the location of manufacture.

time must be allowed to fuse the plating on the connection
to ensure a reliable solder joint. There are several types of
SMT reflow technologies currently used in the industry.
These surface mount power modules can be reliably
soldered using natural forced convection, IR (radiant
infrared), or a combination of convection/IR. For reliable
soldering the solder reflow profile should be established by
accurately measuring the modules pin temperatures.

Figure 34. Pick and Place Location.

Nozzle Recommendations

The module weight has been kept to a minimum by using
open frame construction. Even so, these modules have a
relatively large mass when compared to conventional SMT
components. Variables such as nozzle size, tip style,
vacuum pressure and placement speed should be
considered to optimize this process. The minimum
recommended nozzle diameter for reliable operation is
6mm. The maximum nozzle outer diameter, which will safely
fit within the allowable component spacing, is 9 mm.

Oblong or oval nozzles up to 11 x 9 mm may also be used
within the space available.

Reflow Soldering Information

The Austin SuperLynxTM 12V SMT power modules are large
mass, low thermal resistance devices and typically heat up
slower than other SMT components. It is recommended that
the customer review data sheets in order to customize the
solder reflow profile for each application board assembly.
The following instructions must be observed when soldering
these units. Failure to observe these instructions may result
in the failure of or cause damage to the modules, and can
adversely affect long-term reliability.

Surface Mount Information (continued)

Lead Free Soldering

The –Z version Austin SuperLynx 12V SMT modules are lead­free (Pb-free) and RoHS compliant and are both forward and
backward compatible in a Pb-free and a SnPb soldering
process. Failure to observe the instructions below may
result in the failure of or cause damage to the modules and
can adversely affect long-term reliability.

Pb-free Reflow Profile

Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for Nonhermetic
Solid State Surface Mount Devices) for both Pb-free solder
profiles and MSL classification procedures. This standard
provides a recommended forced-air-convection reflow
profile based on the volume and thickness of the package
(table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu
(SAC). The recommended linear reflow profile using Sn/Ag/Cu
solder is shown in Figure. 36.

MSL Rating

The Austin SuperLynx 12V SMT modules have a MSL rating of
2a.

Storage and Handling

The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages
is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping
and Use of Moisture/Reflow Sensitive Surface Mount
Devices). Moisture barrier bags (MBB) with desiccant are
required for MSL ratings of 2 or greater. These sealed

packages should not be broken until time of use. Once the
original package is broken, the floor life of the product at
conditions of <= 30°C and 60% relative humidity varies
according to the MSL rating (see J-STD-033A). The shelf life
for dry packed SMT packages will be a minimum of 12
months from the bag seal date, when stored at the following
conditions: < 40° C, < 90% relative humidity.

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 (AN04-001).
