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.
