Description: Critical Conduction Mode PFC Controller

Features

* Low Total Harmonic Distortion (THD)
* Dual Output Voltage Control
* Precise Adjustable Output Over-Voltage Protection
* Open-Feedback Protection and Disable Function
* Zero Current Detector
* 160µs Internal Start-up Timer
* MOSFET Over-Curren

Applications

* that operates in critical conduction mode (CRM). It uses voltage mode PWM that compares an internal ramp signal with the error amplifier output to generate MOSFET turn-off signal. Because the voltage mode CRM PFC controller does not need the rectified AC line voltage information, it can save the pow
