Delta DVETR2815D/ES-XXX High reliability hybrid dc-dc converters with integral emi filter Datasheet

DVETR2800D Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
WITH INTEGRAL EMI FILTER
DESCRIPTION
FEATURES
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 is a fault tolerant
magnetic feedback circuit. Operating at a nominal
fixed frequency of 500 kHz per stage, these
regulated, isolated units utilize well-controlled
undervoltage lockout circuitry to eliminate slow startup problems.
•
•
•
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MILPRF-38534 and MIL-STD-883.
This product may incorporate one or more of the
following U.S. patents:
5,784,266
