ABSTRACT:
A lower-cost and more precise control methodology of regulating the output voltage of a Flyback converter from the primary side is provided, which works accurately in either continuous voltage mode (CCM) or discontinuous mode (DCM). The methodology can be applied to most small, medium and high power applications such as cell phone chargers, power management in desktop computers and networking equipment, and, generally, to a wide spectrum of power management applications. Two highly integrated semiconductor chips based on this control methodology are also described that require very few components to build a constant voltage Flyback converter.
