Description
Austin Lynx™ power modules are non-isolated dc-dc converters that can deliver 10 A of output current with full load effi-
ciency of 95% at 3.3 V output. These open frame modules in surface-mount-package enable designers to develop cost-and
space efficient solutions. Standard features include remote ON/OFF, output voltage adjustment, overcurrent and overtem-
perature protection.

SMT Non-Isolated dc-dc Power Modules:
3.0 Vdc - 5.5 Vdc Input, 0.9 Vdc - 3.3 Vdc Output, 10 A
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 reliabiltiy.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
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 time-delay fuse with a maximum rating of 20A.
