High Reliability
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%.
Parallel Up to 5 Units With Current Sharing
Output Voltage Trim Up +10% or Down –20%
Wide Input Voltage Range: 16 to 40 Volts per
MIL-STD-704
Up to 120 Watts Output Power
Radiation Immune Magnetic Feedback Circuit
NO Use of Optoisolators
Undervoltage Lockout
Indefinite Short Circuit Protection
Current Limit Protection

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.
