Description
Austin LynxTM II SIP power modules are non-isolated DC-DC converters that can deliver up to 10A of output current with
full load efficiency of 95% at 3.3V output. These modules provide a precisely regulated output voltage programmable via
an external resistor from 0.75Vdc to 3.63Vdc over a wide range of input voltage (VIN = 2.4 – 5.5Vdc). The Austin LynxTM II
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 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.
