This power supply operates from -36V to -72V and uses synchronous rectification to achieve efficiencies greater than 88% at 10A. It uses a single transistor forward converter with a reset winding and has a maximum duty cycle of 50%. It has input reverse voltage protection, and will regulate to zero load. The isolati……
