AN-6027 - Design of Power Factor Correction Circuit
Using FAN7530
Description
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.
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.

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. TA=25°C, unless otherwise specified.
