FL7930 Description
FL7930 * Single-Stage Flyback and Boundary-Mode PFC Controller for Lighting March 2011 FL7930 Single-Stage Flyback and Boundary-Mode PFC Con.
The FL7930 is an active Power Factor Correction (PFC) controller for low-to high-power lumens applications that operate in Critical Conduction Mode (C.
FL7930 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
FL7930 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
