SOUTHCHIP SEMICONDUCTOR SC3057 PRELIMINARY DATASHEET SOUTHCHIP CONFIDENTIAL SUBJECT TO CHANGE High Frequency Quasi-Resonant Flyback Converter With GaN Integrated 1 Descriptions SC3057 is a high frequency, quasi-resonant flyback PWM converter with 650V GaN integrated (QR/DCM), which can achieve high efficiency and reliability. The converter with x-cap discharge function built-in high voltage start-up circuit through HV pin. Therefore, extremely low standby power consumption and super-fast start-up time can be obtained by HV pin. SC3057 provides an adaptive switching frequency foldback to achieve higher efficiency in the whole loading range. It operates in QR and DCM with valley switching...
