The Bluetooth module in this solution is powered by CX8822 shared with the C port

CX8822 is a step-down DC-DC converter with an input withstand voltage of up to 36V and the ability to achieve precise constant voltage and current

CX8822 has a built-in 50m Ω High side PMOS and 30m Ω Low side NMOS, which can support 3A continuous output current

CX8822 has high-performance load response and input voltage response capabilities, while precise constant voltage and constant current control loops achieve minimal load regulation and linearity

CX8822 does not require external compensation and can rely on its built-in stable loop to achieve constant current and voltage control, while also having cable voltage drop compensation function adjustment rate

CX8855+CX601 realizes QC3.0 fast charging function

The USB-A port supports 18W fast charging to meet daily fast charging needs.
