MI-200
™
Product Highlights
The MI Series is designed for Military
applications and is based on Vicor‘s
second generation family of zero-current-
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 under a
quality system approved to MIL-I-45208
and 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.
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.
