AN-6026 - Design of Power Factor Correction Circuit
Using FAN7529
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
65礎(chǔ). Using a new variable on-time control method,
THD is lower than the conventional CRM boost PFC ICs.
