QBE025A0B Series Power Modules, DC - DC Converters:
42 – 53Vdc input; 12Vdc Output; 25A output current
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 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.
