    SC8101 is a synchronous buck converter with a wide
    input voltage from 5V to 32V. The SC8101 regulates
    the output voltage at a fixed 5.1V or customized
    voltage by setting the divider resistor. It also provides
    high accurate output current limit. The converter
    enters Constant Current (CC) Mode in case the
    output reaches the setting current limit. The total
    output power can be programmed by a resistor,
    which makes it easy for constant power (CP) control.
    SC8101 integrates 45mΩ high side NMOS and
    30mΩ low side NMOS to achieve high efficiency.
    Besides, it provides low side gate driver (LSD) to
    drive external NMOS and works with build-in NMOS.
    SC8101 adopts programmable line drop
    compensation, programmable frequency setting with
    minimum external components, maximum functions
    can be achieved for user’s different applications.
    SC8101 also supports full protections including under
    voltage protection, over voltage protection, short
    current protection and auto-restart, over temperature
    protection.
    SC8101 adopts 19 pin QFN 3x3 package.    产品应用：
