QBVW025A0B Barracuda™ Series; DC-DC Converter Power Modules
36-75Vdc Input; 12.0Vdc, 25.0A, 300W Output
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 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 an integrated part
of sophisticated 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 30 A in the ungrounded input lead of the power supply (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.
