DVTR2800D Series
HIGH RELIABILITY HYBRID
DESCRIPTION
The DVTR 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 DVTR series is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 500 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 MIL­PRF-38534 and MIL-STD-883.
This product may incorporate one or more of the following U.S. patents:
