Product Specification  
Single-Stage PFC Controller  
SG6980  
FEATURES OVERVIEW  
DESCRIPTION  
„
„
Innovative switching-charge multiplier divider  
Multi-vector control for improved PFC output  
transient response  
1:1 Synchronous switching with SYNC  
Average current mode control  
The highly integrated SG6980 is designed for power  
supplies with boost power-factor-correction (PFC).  
It requires very few external components to achieve  
desirable operation and includes versatile protections /  
compensation. It is available in 16-pin DIP and SOP  
packages. The innovative switching-charge multiplier  
divider enhances the PFC circuit’s noise immunity. The  
proprietary multi-vector control scheme provides a fast  
transient response in a low-bandwidth PFC loop, in which  
the overshoot and undershoot of the PFC voltage are  
clamped. If the feedback loop is broken, SG6980 shuts off  
to prevent extra-high voltage on output. The PFC gate  
driver can be synchronized with external SYNC signal  
and the switching noise can be reduced. During start-up,  
the RDY (ready) is pulled low until the PFC output  
voltage reaches the setting level. This signal can be used  
to control the second forward stage for proper power-on  
sequence. In addition, SG6980 provides complete  
protection functions, such as brownout and RI open/short.
