Description

The DV200 series of high reliability, isolated DC-DC converters is operable over a wide (-55 to +100 ) 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 DV200 series are designed and manufactured in a facility qualified to ISO9001 and certified to MILPRF- 38534 and MIL-STD-883.
