FAN7530 Datasheet (Fairchild Semiconductor) - Critical Conduction Mode PFC Controller

FAN7530, Critical Conduction Mode PFC Controller

The FAN7530 is an active power factor correction (PFC) controller for the boost PFC applications that operates in critical 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.

Because the voltage
