Description
The FAN6961 is an 8-pin, boundary-mode, PFC
controller
IC
intended
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 20µA
and the operating current has been reduced to under
6mA. The supply voltage can be up to 25V, maximizing
application flexibility.
