DVFL2800S Series

HIGH RELIABILITY HYBRID

DC-DC CONVERTERS

DESCRIPTION

FEATURES

•

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
