FL7930BMX, FL7930B, Single-Stage Flyback and Boundary-Mode PFC Controller
The FL7930B 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.
Because the voltage-mode
