Product Highlights
The MI-J00 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-J00
family offers exceptional performance in terms of
power density, efficiency, noise, ease of use, and
reliability.
The MI-J00 family meets all steady-state,
transient and under/overvoltage requirements of
MIL-STD-704D/E/F for both 28 Vdc input
(MI-J2X) and 270 Vdc input (MI-J6X), and the
worst case envelope of MIL-STD-1399A for
155 Vdc input (MI-J5X).
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 power
systems.
Fully encapsulated in Vicor’s industry standard
package, the MI-J00 family meets MIL-STD-810
environmental testing requirements for humidity,
fungus, salt-fog, explosive atmosphere,
acceleration, vibration, and shock.
