    Descriptions
    The SC81480Q is a synchronous Buck converter family with
    a wide input voltage from 3V to 36V. The SC81480Q
    regulates the output voltage at customized voltage by
    setting the divider resistors. It provides up to 8A of highly
    efficient output current with current mode control with fast
    loop response.
    The SC81480Q is specifically designed for automotive
    applications. The device incorporates spread spectrum,
    QFN package, symmetrical pinout to optimize the EMI
    performance. Up to 2.2MHz switching frequency could help
    avoid noise sensitive frequency.
    The SC81480Q employs peak current mode control scheme.
    The switching frequency could be synchronized to an
    external clock.
    The SC81480Q offers output over-voltage protection, cycleby-cycle
    peak current limit, output short circuit protection,
    and thermal shutdown protection.
    The SC81480Q is available in 14-pin 4mm X 3.5mm QFN
    package.
