Critical Conduction Mode PFC Controller
The FAN7530 is an active power factor correction (PFC) controller for 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 rectified AC line voltage information, it saves 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, 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 65A. Using a new variable on-time control method, THD is lower than the conventional CRM boost PFC ICs.
