Delta DVHE28SF/HB-XXX High reliability hybrid dc-dc converter Datasheet

DVHE2800S Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
FEATURES
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 MILPRF-38534 and MIL-STD-883.

OUTPUT VOLTAGE TRIM
The output voltage can be trimmed down by
connecting a resistor between the TRIM pin
(PIN 2) and the +V OUT pin (PIN 5), or can
be trimmed up by connecting a resistor
between the TRIM pin (PIN 2) and the OUT
COM pin (PIN 4). The maximum trim range
is +10% up and –10% down. The
appropriate resistor values versus the
output voltage are given in the trim table
below.
