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 sig-

nal. Because 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 neces-

sary for the current-mode CRM PFC controller.

FAN7529 provides many protection functions, such as

over-voltage protection, open-feedback protection, over-

current protection, and under-voltage lockout protection.

The FAN7529 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.
