DVETR2800S Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS WITH INTEGRAL EMI FILTER DESCRIPTION FEATURES The DVETR 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 DVETR series is a fault tolerant magnetic feedback circuit. Operating at a nominal fixed frequency of 500 kHz per stage, these regulated, isolated units utilize well-controlled undervoltage lockout circuitry to eliminate slow startup problems. • • • These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MILPRF-38534 and MIL-STD-883.
