1 / 2 page Product Highlights 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. 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.
