2023-02-12, Key on-off mode PFC controller

The FAN7930C is an active power factor correction (PFC) controller for boost PFC applications that operate in critical conduction mode (CRM). It uses a voltage−mode PWM that compares an internal ramp signal with the error amplifier output to generate a 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 an input voltage−sensing network necessary for a current−mode CRM PFC controller
