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.
