FAN7529 Datasheet PDF - Fairchild

Description

●The FAN7529 is an active power factor correction (PFC) controller for boost PFC applications that operates in crit

●ical conduction mode (CRM). It uses the voltage mode PWM that compares an internal ramp signal with the

●error amplifier output to generate MOSFET turn-off signal.
