Description

Datasheet Jan 1, 2011 The highly integrated FAN4800A/C and FAN4801 /02/2L are specially designed for power supplies that consist of boost PFC and PWM. Apr 27, 2010 shows, the FAN4801 integrated CCM PFC/PWM combination controller is used as the controller for both PFC stage and PWM stage. The basic 11 / 9.3 synchronized operation of PFC and Pwm, ovP, open feedback protection, vFF, power on sequence control, brownout protection. Fan4801 . 75w to 1kw+.
