  • Product Detail
    • Commodity name: SC3057 GAN FET High Frequency Quasi-Resonant Flyback Converter With GaN Integrated, DFN 6*8 mm New And Original
    • Commodity ID: 1342449580687118336

    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 fold-
    back to achieve higher efficiency in the whole loading
    range. It operates in QR and DCM with valley switching for
    high efficiency. And at no load, the IC will operate in burst
    mode to reduce power consumption.
    SC3057 provides functions of low start-up current, fast
    start-up, low standby power consumption. The burst mode
    with extremely low operation current (350uA) can
    significantly reduce standby power consumption to meet
    the efficiency regulations.
    The converter integrates a segment power supply circuit
    for VDD power supply, which is especially suitable for
    applications with wide output voltage range.
    SC3057 offers comprehensive protections 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.
