Product Highlights
Low noise FM control
Up to 90% efficiency
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.
Remote sense
Size: 4.6" x 2.4" x 0.5"
(116,8 x 61,0 x 12,7mm)
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.
