Description
Austin MicroLynxTM II 12V SMT (surface mount technology) power modules are non-isolated DC-DC converters that can deliver up
to 6A of output current with full load efficiency of 89% at 5.0V 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 = 8.3 - 14V). The Austin
MicroLynxTM II 12V series has a sequencing feature, EZ-SEQUENCETM that enable designers to implement various types of output
voltage sequencing when powering multiple voltages on a board.

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 fast-acting 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.
