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 outputs. The outputs are isolated from the input, allowing versatile polarity configurations and grounding connections. 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 filtering.

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 device reliability.
