Description
TM
Austin MicroLynx 12Vdc SIP (single in-line package) power modules are non-isolated dc-dc converters that can
deliver up to 5A of output current with full load efficiency of 89% at 3.3V output. These modules provide precisely
regulated output voltage programmable via external resistor from 0.75Vdc to 5.5Vdc over a wide range of input
voltage (VIN = 10 - 14V). Their open-frame construction and small footprint enable designers to develop cost- and
space-efficient solutions. Standard features include remote On/Off, programmable output voltage and overcurrent
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 fastacting fuse with a maximum rating of 6 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.
