FAN7529M

FAIRCHILD SEMICONDUCTOR  FAN7529M  芯片, 控制器, PFC CRM, SMD, SOIC8

Description

The FAN7529 is an active power factor correction PFC controller for boost PFC applications that operates in crit

ical 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.
