Additional preview pages of the SG6902 datasheet.

The highly integrated SG6902 is designed for power supplies with boost PFC and Flyback PWM.

It requires very few external components to achieve green-mode operation and versatile protections.

It is available in a 20-pin SOP package.

Green-mode PFC and PWM operation No switching of PFC at light loads saves power Low start-up and operating current Innovative switching-charge multiplier-divider Multi-vector control for improved PFC output transient response Interleaved PFC/PWM switching Programmable two-level PFC output voltage Average-current-mode control for PFC Cycle-by-cycle current limiting for.
