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 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.
