The DVTR 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 DVTR 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 325 kHz, per stage, these regulated, isolated units utilize a high speed magnetic feedback design and well controlled under voltage lockout circuitry to eliminate slow start-up problems.
