Description
The LW020 Single-Output-Series Power Modules are
low-profile dc-dc converters that operate over an
input voltage range of 36 Vdc to 75 Vdc and provide
precisely regulated outputs. The outputs are isolated
from the input, allowing versatile polarity configura-
tions and grounding connections. Built-in filtering for
both input and output minimizes the need for external
filtering. The modules have a maximum power rating
of 20 W at a typical full-load efficiency of up to 85%.
