DVWR2800T Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
The DVWR 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 DVWR 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
325 kHz, per stage, 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:
