  • The FAN6961 is an 8-pin, boundary-mode, power factor correction controller 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 maximum on-time of the external switch is programmable to ensure safe operation during AC brownouts. An innovative multi-vector error amplifier is built in to provide rapid transient response and precise output voltage clamping. A built-in circuit disables the controller if the output feedback loop is opened. The startup current is lower than 20 µA and the operating current has been reduced to under 6 mA. The supply voltage can be up to 25 V, maximizing application flexibility.
