This reference design is a multi-output output isolated flyback, working from universal line. The main regulated output is 3.3V@350mA; the 5V and 12V outputs are regulated by means of linear regulators and the 24V output has been generated with a small charge pump. The converter takes advantage of the cascode-flyback topology and quasi-resonant working mode to deliver low EMI and good efficiency at light load.
