Product Summary

The FAN7527BMX is an active power factor correction (PFC) controller for 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. Since the FAN7527BMX does not need rectified AC line voltage information, it saves the power loss of the input voltage sensing network necessary for the current mode CRM PFC controller. The FAN7527BMX provides many protection functions, such as over voltage protection, open-feedback protection, overcurrent protection, and under-voltage lockout protection. The applications of the FAN7527BMX include Adapter, Ballast, LCD TV, CRT TV, SMPS.
