1. Description
The SG6961 is an 8-pin boundary mode PFC controller IC intended for controlling PFC pre-regulators.
The SG6961provides 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.
2. Features
>Boundary Mode PFC Controller
>Low Input Current THD

>Low Operating Current (4.5mA Typical)
>Feedback Open-Loop Protection
>Programmable Maximum On-Time (MOT)
>Output Over-Voltage Clamping Protection
>Clamped Gate Output Voltage 16.5V
