Description
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 network
necessary for the current mode CRM PFC controller.
FAN7530 provides many protection functions such as
over voltage protection, open-feedback protection, overcurrent
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.
