Description

The L Single- and Dual-Output-Series Power Modules are low-profile, dc-dc converters that operate over an

input voltage range of 18 Vdc to 36 Vdc or 36 Vdc to 75 Vdc and provide one or two precisely regulated out-

puts. The outputs are isolated from the input, allowing versatile polarity configurations and grounding connec-

tions. The modules have a maximum power rating of 10 W to 15 W and efficiencies of up to 84% for a 5 V

output and 82% for a 3.3 V output. Built-in filtering for both input and output minimizes the need for external fil-

tering.

Absolute Maximum Ratings

Data Sheet

August 1998

www.DataSheet4U.com

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.

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 flexibility, 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, dc 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.
