Boundary Mode PFC Controller  
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.  
Low Input Current THD  
Controlled On-Time PWM  
Zero-Current Detection  
Cycle-by-Cycle Current Limiting  
Leading-Edge Blanking Instead of RC Filtering  
Low Start-up Current (10µA Typical)  
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
