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.
