Description

The SSTW005A0F Barracuda™ series power modules are isolated dc-dc converters that operate over an ultra-wide input voltage
range of 36Vdc -75Vdc and provide a single precisely regulated output voltage at 3.3Vdc. This series is a low cost, smaller size
alternative to the existing LW/LAW/LC/SC/SW with enhanced performance parameters. The output is fully isolated from the input,
allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency of 87.5% typical at full
load. Built-in filtering for both input and output minimizes the need for external filtering. The module is fully self-protected with
output over-current and over-voltage, over-temperature and input under voltage shutdown control. Optional features include
negative or positive on/off logic and SMT connections.

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
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 3 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.
