ON FAN6961SY

临界传导（BCM）60kHz

Overview

The FAN6961SY is an 8-pin, boundary-mode, PFC controller IC intended for controlling PFC pre regulators. The FAN6961SY 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 multivector 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 start-up current is lower than 20μA and the operating current has been reduced to under 6mA. The supply voltage can be up to 25V, maximizing application flexibility.
