    Descriptions
    SC3058A is a high frequency, flyback PWM converter with
    700V GaN integrated (QR/DCM/CCM), which can achieve
    high efficiency and reliability.
    SC3058A provides an adaptive switching frequency foldback
    to achieve higher efficiency in the whole loading
    range. At heavy load or full load, it operates up to
    maximum switching frequency. When loading decreases,
    it operates in green mode with valley switching for high
    efficiency. And at no load, the IC will operate in Burst
    mode to reduce power consumption.
    It provides functions of low start-up current, fast start-up,
    low standby power consumption. The burst mode with
    extremely low operation current (240uA) and significantly
    reduces standby power consumption to meet the
    efficiency regulations.
    The SC3058A offers comprehensive protection to prevent
    the circuit from damage under abnormal conditions.
    Furthermore, the features of frequency jittering and smart
    driving function can minimize the noise and improve EMI
    performance.
