DC-DC Converters, 200-250 Watt Family
World's Most Advanced Ultra High Density Single and Triple Output DC-DC Converters Up to 252 Watts 28, 48, and 300 VDC Input
Evaluation Boards and Triple Output Modules Available
DESCRIPTION
MicroVerter modules are high density DCDC converters designed for use in telecom 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 produce up to 252 watts in a tiny package.
