  • Patent number: 7209372
    Abstract: Disclosed herein is a flyback converter with a synchronous rectifier which is applied to a power supply of a portable computer such as a notebook PC. The flyback converter is operated in a critical conduction mode to turn on/off a main switch at a zero crossing point of an output voltage. The flyback converter is also adapted to supply a driving voltage to a synchronous switch using the output voltage. Therefore, there is no need for a secondary auxiliary coil of a transformer and for a Schottky diode to be connected in parallel with the synchronous switch, resulting in simplification in circuit design.
