描述 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.
