Pengyuansheng 10W vertical dual coil wireless charging supports 1A1C dual output, with the USB-C port supporting 18W fast charging, providing a fast charging experience for connected devices. At the same time the USB-A port can power the mouse and small fan, making it very suitable for office desk applications. This wireless charger is equipped with three independent synchronous buck circuits, corresponding to wireless charging and two outputs.

• Output: Double coil

• DC input: 15V3.5A

• Wireless charging output: 10W/7.5W/5W

• USB-C output: with three fixed voltage ranges of 5V3A, 9V2A, and 12V1.5A

• USB-A output: 5V2.4A

The entire wireless charging solution adopts a wireless charging master chip+CX8825+USB-C interface, which uses a 3.5A output current power supply chip and a HUSB338L protocol chip. The USB-A interface uses a 3.5A output current DC-DC buck IC for power supply.

The wireless charging and step-down power supply chip uses the CX8825, which is a step-down DC-DC converter with an input withstand voltage of up to 36V and can achieve precise constant voltage and constant current

CX8825 has a built-in 50m Ω High side PMOS and 30m Ω Low side NMOS, which can support 3A continuous output current and adjustable output voltage, with a maximum support of 100% duty cycle

CX8825 has high-performance load response and input voltage response capabilities, while precise constant voltage and constant current control loops achieve minimal load and linear adjustment rates

CX8825 does not require external compensation, and its peripheral devices are simplified. It can rely on its built-in stable loop to achieve constant current and constant voltage control, and also has cable voltage drop compensation function
