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 are robust and effective input and
output filters which provide dramatically reduced
input and output noise performance when compared
to other manufacturers competing devices.
Operating at a nominal fixed frequency of 500 kHz,
these regulated, isolated units utilize a high speed
magnetic feedback design and 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.
This product may incorporate one or more of the
following U.S. patents:
