FAN7530 - Critical Conduction Mode PFC Controller

Datasheet Summary

Description

The FAN7530 is an active power factor correction (PFC) controller for the boost PFC applications that operates in critical conduction mode (CRM).

It uses the voltage mode PWM that compares an internal ramp signal with the error amplifier output to generate MOSFET turn-off signal.

Features

  • Low Total Harmonic Distortion (THD).
  • Precise Adjustable Output Over-Voltage Protection.
  • Open-Feedback Protection and Disable Function.
  • Zero Current Detector.
  • 150µs Internal Start-up Timer.
  • MOSFET Over-Current Protection.
  • Under-Voltage Lockout with 3.5V Hysteresis.
  • Low Start-up (40µA) and Operating Current (1.5mA).
  • Totem Pole Output with High State Clamp.
  • +500/-800mA Peak Gate Drive Current.
  • 8-pin DIP or 8-pin SOP.
