    EVB_SY22813C

    SY22813C is a PWM/PFM controller with several features to enhance performance of Flyback converters that targeting at adapter or charger applications. It drives Flyback controller in the Quasi-Resonant mode for higher efficiency and better EMI performance. SY22813C adopt burst mode control for improved efficiency. The output current is detected by internal primary detection technology to achieve more reliable Over Current Protection and Short Circuit Protection.
