Description
The SSTW001A3B 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 12Vdc. 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 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.
