This reference design is a 12-V/5-A and 50-V/1-A isolated dual-output auxiliary power supply. Secondary-side regulation improves the line and load regulation using UCC28742. DCM valley-switching operation enable higher efficiency at light load. All components height below 20 mm enable slim TV application.
