FAN4802NY Datasheet PDF - Fairchild

●Description

●The highly integrated FAN4800A/C and FAN4801/1S/2/2L 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.

●Features
