FAN4800AS - ON Semiconductor

FAN4800AS PFC/PWM Controller Combination

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 th.
