FAN7530MX

Product Summary

The FAN7530MX 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. 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 necessary for the current mode CRM PFC controller. The FAN7530MX provides many protection functions, such as over voltage protection, open-feedback protection, overcurrent protection, and under-voltage lockout protection. The FAN7530MX 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.
