High-Efficiency 100W Dual-C and Single-A Port Car Charger Fast Charging Solution
January 01, 2025

        In the era of rapid automotive technology advancement and the growing demand for digital devices, CXW technology has introduced the 100W dual USB-C and USB-A car charger solution. This innovative solution features two USB-C ports (C1 and C2) and one USB-A port, designed to meet the fast charging needs of multiple devices simultaneously. The C1 port supports up to 100W fast charging, while the total output power of the charger is 65W, with dual 5V shared output to achieve a 100W multi-port power distribution.

This 45W GaN dual-port fast charger is designed with three PCBA boards and comes equipped with dual USB-C output ports. Both ports support fast charging, ensuring that two different devices can be charged rapidly at the same time.


Key Features and Specifications:

1. High Output Power

  • C1 Port (USB-C): Supports up to 100W fast charging.
  • C2 Port (USB-C): Supports up to 30W fast charging.
  • USB-A Port: Supports up to 18W QC fast charging.

      Combined Output:

  • C1 + C2: Up to 95W
  • C1 + A: Up to 118W
  • C2 + A: 5V shared
  • C1 + C2 + A: 65W + 5V shared

2. Advanced Circuit Design

  • The charger is designed with a combination of one buck-boost circuit and one buck circuit. The buck-boost circuit uses the CX8836 controller, while the buck circuit uses CX8855/CX8576 converters.
