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.
Fully encapsulated in Vicor’s industry standard
package, the MI-Series meets MIL-STD-810
environmental requirements for humidity, fungus,
salt-fog, explosive atmosphere, acceleration,
vibration, and shock.
Standard features such as wide output trim-
ming/programming, current limiting, remote
sense, output inhibit, and latching OVP and OTP
combine to offer the highest degree of protection,
versatility, and reliability for power systems.
