Product Highlights
The MI-200 family of DC-DC converters is
designed for applications utilizing distributed
power architectures. Based on Vicor’s VI-200 /
VI-J00 family of zero-current switching,
component level DC-DC converters, the MI-200
family offers exceptional performance in terms of
power density, efficiency, noise, ease of use, and
reliability.
