Product Specification Single-Stage PFC Controller www.DataSheet4U.com SG6980 DESCRIPTION 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.
