Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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 device reliability.
* Forced convection—200 lfpm minimum. Higher ambient temperatures possible with increased airflow and/or decreased power output. See the
Thermal Considerations section for more details.
Electrical Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions.

Fusing Considerations
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 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 20 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 for further information.
