DVTR2800T Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
The DVTR series of high reliability DC-DC converters
is operable over the full military (-55 °C to +125 °C)
www.DataStheemet4pUe.croamture range with no power derating. Unique
to the DVTR series is a fault tolerant magnetic
feedback circuit. Operating at a nominal fixed
frequency of 325 kHz per stage, 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:
