DVTR2800D Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION The DVTR series of high reliability DC-DC converters is operable over the full military (-55 °C to +125 °C) www.DataSheet4U.com temperature range with no power derating. Unique to the DVTR 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. Th.

DVTR2800D Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION The DVTR series of high reliability DC-DC converters is operable over the full military (-55 °C to +125 °C) www.DataSheet4U.com temperature range with no power derating. Unique to the DVTR 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. These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MILPRF-38534 and MIL-STD-883.
