SG6902
Overview
The highly integrated SG6902 is designed for power supplies with boost PFC and Flyback PWM. It requires very few external compo.
- 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 PFC/PWM PFC over-voltage and under-voltage protections PFC and PWM feedback open-loop protection Brownout protection Over-temperature protection
