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. This product may incorporate one or more of the following U.S. patents: 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673

Dependant on output voltage. Time for output voltage to settle within 1% of its nominal value. Derate linearly to 0 at 135°C. Verified by qualification testing. Half load at +VOUT and half load at –VOUT. Up to 70% of the total power or current can be drawn from any one of the two .
