DV200-2800S Series
HIGH RELIABILITY
DC-DC CONVERTERS
DESCRIPTION
The DV200 series of high reliability, isolated DC-DC
converters is operable over a wide (-55 °C to +100
°C) temperature range with no power derating.
Unique to the DV200 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.
This product may incorporate one or more of the
following U.S. patents:
