DATA SHEET www.onsemi.com PFC/PWM Controller Combination FAN4800AS/CS/01S/2S Description The highly integrated FAN4800AS/CS/01S/02S parts are specially designed for power supplies that consist of boost PFC and PWM. They require very few external components to achieve versatile protections / compensation. They are available in 16−pin DIP and SOP packages. The PWM can be used in either current or voltage mode. In voltage mode, feed−forward from the PFC output bus can reduce the secondary output ripple. Compared with older productions, ML4800 and FAN4800, FAN4800AS/CS/01S/02S have lower operation current that saves power consumption in external devices. FAN4800AS/CS/01S/02S have accurate 49.9% maximum duty of PWM that makes the hold−up time longer.
