Product Details
DESCRIPTION
The SG6961 is an 8-pin boundary mode PFC controller IC intended for
controlling PFC pre-regulators. The SG6961 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 is under 4.5mA. The supply voltage can be up to
20V, maximizing application flexibility.
