DVHF2800D Series

HIGH RELIABILITY HYBRID

DC-DC CONVERTERS

DESCRIPTION

The DVHF series of high reliability DC-DC converters is operable over the full military (-55 °C to +125 °C) temperature range with no power derating. Unique to the DVHF series is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 450 kHz, these regulated, isolated units utilize well controlled undervoltage lockout circuitry to eliminate slow start-up problems. These converters are designed and manufactured in

a facility qualified to ISO9001 and certified to

MIL-PRF-38534 and MIL-STD-883.

This product may incorporate one or more of the

following U.S. patents:
