A TOP223Y?based switching power supply with multi?channel output single?end flyback AC/DC module was de?signed. Peripheral circuits are analyzed by TOP Switch series single?chip switching power supply chip and the feedback system composed of TL431 and PC817A. The AC/DC switching power supply whose voltage stabilization adjusting weight is 0.6 and 0.4 with the outputs of +5V/3A and +12V/1A was designed. The experimental results show that the switching power supply has high efficiency,small ripple,high output accuracy and high stability.
