3.3 Vdc and 5.0 Vdc Input, 1.5 Vdc - 3.3 Vdc Output, 6A
Austin Series Non-Isolated SMT DC - DC Power Modules:
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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 device reliability. Input voltage range of VIN = 3.0V — 3.6V is listed as 3.3 VIN and
input voltage range of VIN = 4.5V — 5.5V is listed as 5.0 VIN.

Fusing Considerations
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 stand-alone operation to an
integrated part of a sophisticated 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 normal blow fuse with a maximum rating of 10A (see Safety and Reliability Specifications).
