HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
WITH INTEGRAL EMI FILTER
DESCRIPTION
The DVETR 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 DVETR series are robust and effective
input and output filters which provide dramatically
reduced input and output noise performance when
compared to other manufacturers competing
devices. Operating at a nominal fixed frequency of
500 kHz, these regulated, isolated units utilize a high
speed magnetic feedback design and 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:
