FAN7530

Critical Conduction Mode PFC Controller

Features

Description

Low Total Harmonic Distortion (THD)

Precise Adjustable Output Over-Voltage Protection

Open-Feedback Protection and Disable Function

Zero Current Detector

The FAN7530 is an active power factor correction (PFC)

controller for the 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. Because the voltage mode CRM PFC controller

does not need the rectified AC line voltage information, it

can save the power loss of the input voltage sensing net-

work necessary for the current mode CRM PFC control-

ler.

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

FAN7530 provides many protection functions such as

over voltage protection, open-feedback protection, over-

current protection, and under-voltage lockout protection.

The FAN7530 can be disabled if the INV pin voltage is

lower than 0.45V and the operating current decreases to

65µA. Using a new variable on-time control method,

THD is lower than the conventional CRM boost PFC ICs.
