Fairchild Semiconductor

File Size:

0.96 MB

Description:

Critical Conduction Mode PFC Controller

Features

* Additional OVP Detection Pin Input Voltage Absent Detection Circuit Maximum Switching Frequency Limitation Internal Soft-Start and Overshoot-less Control Internal Total Harmonic Distortion (THD) Optimizer Preci

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 l
