    DescriptionsThe SC87580Q is a fully integrated USB PD solution. It integrates a
    Buck-boost converter with 4 integrated power switches and a USB PD controller. The SC87580Q operates over 4.5V to 36V wide input voltage and can output 3.3V to 22.5V voltage to support a variety of applications.
    It also supports up to 5A continuous output current under certain input supply range. The SC87580Q supports USB PD3.1 with PPS and backward supports
    DCP schemes for Battery Charging specification (BC1.2), The 3A
    Divider Mode. It also supports QC2.0/QC3.0, Huawei FCP as well. The SC87580 -boost converter employs current mode control scheme. The switching frequency could be set at
    280kHz/420kHz/560kHz through I2C. The SC87580Q also provides optional spread spectrum to optimize EMI performance.
    The SC87580Q supports a flexible power management state machine when the battery voltage is low, or the temperature is high. When two
    SC87580Q are used in dual PD ports, the internal power sharing logic can smartly distribute the total power. The SC87580Q offers input over-voltage protection, output over-voltage
    protection, cycle-by-cycle current limit, DP/DM/CCx short to battery
    protection, output short circuit protection, average output current limit and thermal shutdown protection The SC87580Q is available in 22-pin 4mm X 5mm Wettable Flank QFN
