Features

* Additional PFC-Ready Function (FL7930C Only) Input-Voltage-Absent-Detection Circuit Maximum Switching Frequency Limitation Internal Soft-Start with Overshoot Prevention Internal Total Harmonic Distortion

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 CRM PFC controller does not need rectified AC line voltage information, it saves the power l
