DESCRIPTION
MicroVerter modules are high density DC-
DC converters designed for use in tele-
com and other centralized modular and
distributed power applications. Three
input voltage ranges are available and
all use metal PC boards, planar transformers,
and surface mount construction to pro-
duce up to 252 watts in a tiny package.
