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

trimming/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.
