63W dual port PD fast charging, compatible with QC3.0 car charging: It is a dual circuit car charging solution that supports USB PD and QC3.0, with a total power of 63W.

USB-A supports QC3.0 fast charging with a maximum power of 18W.

The USB-C port supports PD protocol for fast charging, with a maximum power of up to 45W.

The PDO message shows that the USB-C port also supports the USB PD3.0 fast charging standard, with five fixed voltage ranges of 5V3A, 9V3A, 12V3A, 15V3A, and 20V2.25A, as well as two PPS voltage ranges of 3.3-11V/3A and 3.3-20V/2.25A.

The parameters are as follows:

Input: DC12-24V

OUTPUT: Port C: DC 5V 3A/9V 3A/12V 3A/15V 3A/20V 2.25A

                Port A: 5V 3A/9V 2A/12V 1.5A

The C port of the 1A1C 63W intelligent fast charging vehicle adopts an independent up/down CX8838B, which is controlled by the protocol chip CX2965C for output. The A port adopts the design architecture of an integrated buck chip CX8830 to complete the QC3.0 fast charging function.

This 63W dual USB interface, 1A1C car charging is quite popular in the market, and supports up to 18W and 45W outputs respectively. When the dual ports output simultaneously, the total power is 63W, which can meet the fast charging needs of two devices at the same time, bringing users an unexpected fast charging experience.

The 63WDC dual C port scheme has two input channels. The USB-C port is boosted and lowered by a voltage controller paired with four NMOSs, and protocol fast charging is achieved through CX2965C. The USB-C port can achieve 45W fast charging output; The USB-A port achieves 18W QC fast charging, which has high integration and only requires a small number of devices, effectively simplifying the circuit and reducing costs and has a high overall cost-effectiveness.
