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.
●Features
●Low Total Harmonic Distortion (THD)
●Precise Adjustable Output Over-Voltage Protection
●Open-Feedback Protection and Disable Function
●Zero Current Detector
●150µs Internal Start-up Timer
●MOSFET Over-Current Protection
●Under-Voltage Lockout with 3.5V Hysteresis
●Low Start-up (40µA) and Operating Current (1.5mA)
●Totem Pole Output with High State Clamp
●+500/-800mA Peak Gate Drive Current
●8-Pin DIP or 8-Pin SOP
●Applications
●Adapter
●Ballast
●LCD TV, CRT TV
●SMPS
