FL7930CMX Datasheet Single-stage Flyback And Boundary-mode Pfc Controller

Manufacturer: Fairchild (now onsemi)

Overview: FL7930C — Single-Stage Flyback and Boundary-Mode PFC Controller for Lighting October 2013 FL7930C Single-Stage Flyback and Boundary-Mode PFC Controller for.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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.

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

  • PFC-Ready Signal.
  • VIN-Absent Detection.
  • Maximum Switching Frequency Limitation.
  • Internal Soft-Start and Startup without Overshoot.

  • 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.
