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

This product may incorporate one or more of the
following U.S. patents:
