Delta DVFL2812SRDL/K-XXX High reliability hybrid dc-dc converter Datasheet

DVFL2800S Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
FEATURES
The DVFL 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 DVFL series is a magnetic feedback circuit
that is radiation immune. Operating at a nominal
fixed frequency of 500 kHz, these regulated, isolated
units utilize well-controlled undervoltage lockout
circuitry to eliminate slow start-up problems. The
current sharing function allows a maximum of five
units to be connected in parallel to boost the total
output power to 5 times. The output voltage is
trimmable up to +10% or down –20%.

•
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:

OUTPUT VOLTAGE TRIM
The output voltage can be trimmed down by
connecting a resistor between the TRIM pin
(PIN 3) and the +V OUT pin (PIN 7), or can
be trimmed up by connecting a resistor
between the TRIM pin (PIN 3) and the OUT
COM pin (PIN 8). The maximum trim range
is +10% up and –20% down. The
appropriate resistor values versus the
output voltage are given in the trim table
below.
