Description
The L Single- and Dual-Output-Series Power Modules are low-prole, 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 congurations and grounding connections.
The modules have a maximum power rating of 10 W to 15 W and efciencies of up to 84% for a 5 V output and
82% for a 3.3 V output. Built-in ltering for both input and output minimizes the need for external ltering.
