Description
Austin Lynx
TM
12V SMT (surface mount technology) power modules are non-isolated DC-DC converters that can deliver up to 10A of
output current with full load efficiency of 93% at 3.3V output. These modules provide a precisely regulated output voltage ranging
from 1.2Vdc to 5.5Vdc over a wide range of input voltage (V
IN
= 10 – 14Vdc). Their open-frame construction and small footprint
enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, remote sense, output
voltage adjustment, overcurrent and overtemperature protection.

TM
10A: Non-Isolated DC-DC Power Modules
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 15 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.
