DVHE2800S Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
The DVHE series of high reliability DC-DC
converters is operable over the full military (-55 °C to
+125 °C) temperature range with no power derating.
Operating at a fixed frequency, these regulated,
isolated units utilize well controlled undervoltage
lockout circuitry to eliminate slow start-up problems.
The DVHE is optimized for low voltage applications
with high efficiency synchronous rectification and fast
transient response.
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
