Product Highlights

The MI-Series is designed for

military applications and is based

on Vicor’s 1st Generation family of

zero-current/zero-voltage switching,

component level DC-DC converters.

Operating at frequencies in excess

of 1MHz, the MI-Series offers

state-of-the-art performance in

terms of power density, efficiency,

noise, ease of use, and reliability.

All units are manufactured in ISO

9001-registered facilities. Full

epoxy encapsulation in Vicor’s

industry standard package

enables the MI-Series to meet

MIL-STD-810 environmental

requirements for humidity,

fungus, salt, fog, explosive

atmosphere, acceleration,

vibration, and shock. (See page 32.)

Standard features such as wide

output trimming/programming,

current limiting, remote sense,

output inhibit, and latching 

OVP and OTP combine to offer 

a high degree of protection,

versatility, and reliability for

military power systems.
