DVEHF2800T Datasheet, PDF (1/11 Pages) Delta Electronics, Inc. – HIGH RELIABILITY HYBRID DC-DC CONVERTERS WITH INTEGRAL EMI FILTER

DVEHF2800T Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
WITH INTEGRAL EMI FILTER
DESCRIPTION
The DVEHF 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 DVEHF series is a fault tolerant
magnetic feedback circuit. Operating at a nominal
fixed frequency of 450 kHz per stage, 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.
