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 an integrated

part of complex power architecture. To preserve maximum flexibility, internal fusing is not included. Always use an input line fuse,

to achieve maximum safety and system protection. The safety agencies require a time-delay or fast-acting fuse with a maximum

rating of 25 A in the ungrounded input connection (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.
