This application note describes a power factor correction (PFC) circuit using the FAN6961.

Both the

of this controller, as well as the operation of the power factor correction circuit, are presented in detail. Based on the proposed design guideline, a design example with detailed parameters demonstrates the performance of the controller. Introduction The FAN6961 PFC controller is an 8-pin Boundary Current Mode (BCM) IC intended for controlling PFC pre-regulators. The FAN6961 provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximu.
