FL7930 Datasheet Single-stage Flyback And Boundary-mode Pfc

Manufacturer: Fairchild (now onsemi)

Overview: FL7930 — Single-Stage Flyback and Boundary-Mode PFC Controller for Lighting March 2011 FL7930 Single-Stage Flyback and Boundary-Mode PFC Controller for.

General Description

The FL7930 is an active Power Factor Correction (PFC) controller for low-to high-power lumens 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 loss of an input voltage sensing network necessary for a current-mode CRM PFC controller.

Key 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 (THD) Optimizer Precise Adjustable Output Over-Voltage Protection Additional OVP Detection Pin (FL7930B Only) Open-Feedback Protection and Disable Function Zero-Current Detector 150µs Internal Startup.
