Description
The   FAN6961   is   an   8-pin,   boundary-mode,   PFC
controller 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 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 礎(chǔ) and the operating
current has been reduced to under 6 mA. The supply
voltage can be up to 25 V, maximizing application
flexibility.
