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 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 sig-

nal. Since the voltage mode CRM PFC controller does

not need rectified AC line voltage information, it saves

the power loss of the input voltage sensing network nec-

essary for the current mode CRM PFC controller.

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.
