TQD SERIES - DUAL OUTPUT, 100 WATT
DESCRIPTION
The TQD DC/DC converters are high power, dual output,
fully isolated converters that feature high efficiency, 1500
VDC isolation, and open-frame packaging. The TQD
family allows board designers to deliver any combination
of power from either output, up to each model鈥檚 maximum
rating. The TQD series is available in 5V/3.3V or
3.3V/2.5V combinations. The TQD uses planar
magnetics and has an MTBF of over a million hours.
