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 output voltage is trimmable up to +10% or down 20%.
