DVHV2800S Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
The DVHV 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 DVHV series is a magnetic feedback
circuit that is radiation immune. Operating at a
nominal fixed frequency of 475 kHz, these regulated,
isolated units utilize well controlled undervoltage
lockout circuitry to eliminate slow start-up problems.
The output voltage is trimmable up to +10% or down
–20%.
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:
