Product Highlights
The MI-J00 family of miniaturized
DC-DC converters is designed for
military applications utilizing
distributed power architectures.
Based on Vicor’s 1st Generation
family of zero-current/zero-voltage
switching, component-level,
DC-DC converters, the MI-J00
family offers state-of-the-art
performance in terms of power
density, efficiency, noise, ease of
use, and reliability.
The MI-J00 family is designed to
exceed all steady-state, transient
and under/overvoltage
requirements of MIL-STD-704D/E
for both 28Vdc input (MI-J20) and
270Vdc input (MI-J60), and the
worst case envelope of DOD-STD-
1399A for 155Vdc input.
The output voltage can be externally
trimmed or programmed from
50% to 110% of nominal output.
Current limiting, remote sense,
and an inhibit pin all combine to
offer a high degree of protection,
versatility, and reliability for
military power systems.
All units are manufactured
in ISO 9001-registered facilities.
Full epoxy encapsulation in
Vicor’s industry standard
package enables the MI-J00
family units to meet MIL-STD-810
environmental testing
requirements for humidity,
fungus, salt fog, explosive
atmosphere, acceleration,
vibration, and shock. (See page 32.)
