Design Features
The 6804PS(-1) is a two-stage, switching power supply that provides the
following outputs:
To maximize efficiency and to minimize individual component
temperature rise, the 6804PS(-1) has a two-stage design comprising an
input Buck converter feeding a high-efficiency push-pull output stage.
Overall efficiency exceeds 75% and individual component temperature
rise is minimized by operating both converts at high voltage and low
current, as well as using synchronous rectifiers and Schottky rectifier
diodes on the output stage. The power supply works from 90 to 265 VAC.
