FAN7930C - Critical Conduction Mode PFC Controller

Datasheet Summary

Description

The FAN7930C is an active power factor correction (PFC) controller for boost PFC applications that operate in critical conduction mode (CRM).

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

Features

  • PFC-Ready Signal Input Voltage Absent Detection Maximum Switching Frequency Limitation Internal Soft-Start and Startup without Overshoot Internal Total Harmonic Distortion (THD) Optimizer Precise Adjustable Output Over-Voltage Protection Open-Feedback Protection and Disable Function Zero-Current Detector (ZCD) 150μs Internal Startup Timer MOSFET Over-Current Protection (OCP) Under-Voltage Lockout with 3.5V.
