MI-J62-MY-05

Product Summary

The MI-J62-MY-05 of miniaturized DC-DC converter which is designed for military applications utilizing distributed power architectures. Based on Vicors 1st Generation family of zero-current/zero-voltage switching, component-level, DC-DC converters, the MI-J62-MY-05 offers state-of-the-art performance in terms of power density, efficiency, noise, ease of use, and reliability. The MI-J62-MY-05 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 Vicors 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.
