SMPS is widely applied in computers and other electric equipment, the advantage of which is its small size and high efficiency. The development trend of it is miniaturization. DC/DC converter is the core part of SMPS. A Flyback DC/DC converter using TOPSwitch is designed. Main circuit, control circuit and feedback circuit designs are included. The circuit is manufactured and tested. The experimental results show the output voltage is stable, the circuit is simple, the size is small and the design process is simplified.
