FAN4802 - Fairchild Semiconductor

FAN4802 PFC/PWM Controller Combination

The highly integrated FAN4800A/C and FAN4801/02/2L 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 .
