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 reliabiltiy.

* Forced convection—1.5 ms–1 (300 lfm) minimum. Higher ambient temperatures are possible with increased airflow and/or decreased power
output. See the Thermal Considerations section for more details.
† The –40 °C operation is optional. See Ordering Information section.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power SIP can be used in a wide variety of applications, ranging from simple stand-alone operation to an
integrated part of a 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 normal-blow
fuse with a maximum rating of 10 A (see Safety Considerations section). To aid in the proper fuse selection for the given appli-
cation, information on inrush energy and maximum dc input current is provided. Refer to the fuse manufacturer’s data for fur-
ther information.
