Product Highlights
The MI-Series is designed for
applications utilizing distributed
power architecuture based on
Vicor’s 1st Generation family of
zero-current/zero-voltage switching,
component level DC-DC converters.
Operating at frequencies in excess
of 1 MHz, the MI-Series offers
state-of-the-art performance in
terms of power density, efficiency,
noise, ease of use, and reliability.
