Description
The 12V Austin Lynx
TM
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 (V
IN
= 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.

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.
