Description:

Critical Conduction Mode PFC Controller

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 Out

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. Because the voltage-mode CRM PFC controller does not need rectified AC line voltage information, it saves the power lo
