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.

See EMC Considerations section

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 architectures. 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 time-delay fuse with a maximum rating of 6 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.
