36 Vdc to 75 Vdc Inputs; 20 W
LW020 Single-Output-Series Power Modules:
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the devices. These are
absolute stress ratings only. Functional operation of the devices 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.
* Maximum case temperature varies based on power dissipation. See derating curve, Figure 16, for details.
Electrical Specications
Unless otherwise indicated, specications apply over all operating input voltage, resistive load, and temperature
conditions.
Table 1. Input Specications
Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated 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 exibility, internal fus-
ing 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 5 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.
