ICRO ERTER DC-DC Converters, 200-250 Watt Family
V
RO
Evaluation Boards and Triple Output Modules Available
World’s Most Advanced Ultra High
Density Single and Triple Output
DC-DC Converters
Up to 252 Watts
28, 48, and 300 VDC Input
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.
