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 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.
