Description
The SW/SC series power modules are isolated dc-dc converters that operate over a wide range of input voltage (V
IN
= 18 - 36Vdc
for SC modules and V
IN
= 36 – 75Vdc for SW modules) and provide a single precisely regulated output. This series is a low cost,
smaller size alternative to the existing LW/LAW/LC with enhanced performance parameters. The output is fully isolated from the
input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency, typical efficiency
of 86% for 5.0V/3A. Built-in filtering for both input and output minimizes the need for external filtering.
§ This product is intended for integration into end-use equipment. All of the required procedures of end-use equipment should be followed.

Absolute Maximum Ratings
18-36Vdc & 36-75Vdc Input; 3.3-15Vdc Output; 1-3.5A Output Current
Data Sheet
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
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 3A
(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.
