FAN7930B - PFC Controller
The FAN7930B is an active power factor correction (PFC) controller for boost PFC applications that operate in critical conduction mode (CRM).
It uses a voltage *mode PWM that compares an internal ramp signal with the error amplifier output to generate a MOSFET turn *off signal.
