    Descriptions
    The SC81410Q and SC81414BQ are synchronous buck
    converter with a wide input voltage range from 3V to 36V,
    providing 1A current capability options. The converter
    regulates the output voltage at customized voltage through
    setting the divider resistors. It also provides highly efficiency
    output current and fast loop response with current mode
    control.
    The SC81410Q and SC81414BQ are specifically designed
    for automotive applications. The device integrates useroptional
    spread spectrum and QFN package, whose
    symmetrical pinout to optimize the EMI performance. In
    order to minimize solution size, two fixed switching
    frequency options are available to remove RT resistor. The
    switching frequency can also be synchronized to external
    clock through multiplexing EN/SYNC pin. For fixed
    frequency parts, a power good function is available by the
    PG pin. In addition, the device incorporates highly efficient
    PFM mode.
    The SC81410Q and SC81414BQ employ both peak current
    limit and valley current limit to help protect the device from
    overload as well as provides short-period heavy current
    capability. It also provides thermal shutdown, input UVLO,
    output short-circuit protection to enable systematical robust
    operation.
