DVFL2800D Datasheet, PDF (1/19 Pages) Delta Electronics, Inc. – HIGH RELIABILITY HYBRID DC-DC CONVERTERS

DVFL2800D Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
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 MIL-
PRF-38534 and MIL-STD-883.
