PMP5515.1, Isolated Flyback Reference Design for Industrial Applications (3.3V @ 350mA)

PMP5515.1, Isolated Flyback for Industrial Applications (3.3V@350mA). This reference design is a multi-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 cascade-flyback topology and quasi-resonant working mode to deliver low EMI and good efficiency at light load
