DVEHF2800T Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
WITH INTEGRAL EMI FILTER
DESCRIPTION
www.DataSTcheohenet4vUDe.crVtoeEmrHs FissoepreiersabolfehoigvherrethlieabfuililtlymDilCita-DryC(-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.
This product may incorporate one or more of the
following U.S. patents:
5,784,266
5,790,389
5,963,438
5,999,433
6,005,780
6,084,792
6,118,673
