Note: 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 converter is not internally fused. An input line fuse must be used in application.
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 5A. 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.
Note: Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and
temperature conditions.
