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 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%.

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

Fault Tolerant Magnetic Feedback Circuit

NO Use of Optoisolators

Undervoltage Lockout

Indefinite Short Circuit Protection

Current Limit Protection


