    SC8101Q is a synchronous buck converter with a
    wide input voltage from 4.4V to 32V. The SC8101Q
    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.
    SC8101Q 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.
    SC8101Q adopts programmable line drop
    compensation, programmable frequency setting with
    minimum external components, maximum functions
    can be achieved for user’s different applications.
    SC8101Q also supports full protections including
    under voltage protection, over voltage protection,
    short current protection and auto-restart, over
    temperature protection.
