Additional preview pages of the FL7930C datasheet.

The FL7930C 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.

! PFC-Ready Signal ! VIN-Absent Detection ! Maximum Switching Frequency Limitation ! Internal Soft-Start and Startup without Overshoot ! Internal Total Harmonic Distortion (THD) Optimizer ! Precise Adjustable Output Over-Voltage Protection ! Open-Feedback Protection and Disable Function ! Zero-Current Detector (ZCD) ! 150 µs Internal Startup Timer ! MOSFET Over-Current Protection (OCP) ! Under-Voltage Lockout with 3.5 V Hysteresis ! Low Startup and Operating Current ! Totem-Pole Output with High.
