DIY Thunderbolt 3 Expansion Dock, using an Intel reference motherboard extracted from a Belkin expansion dock, flashed with Razer CoreX firmware. The power section utilizes a 750W CSPS power supply with platinum efficiency. I designed my own PCB board, thanks to JLC support. It uses the TI43060 solution with a 12V input and 20V output module, achieving 95% efficiency and a maximum output current of 10A.
I want to express my gratitude to Leaves on Zhihu for explaining the Thunderbolt concept and sharing firmware. Also, I want to thank Shuangqiu for designing the CSPS power board and JLC for their support of PCBs for enthusiasts.
This version of the boost circuit has some issues in the layout, with noise from MLCC during light loads. After making changes, I will open-source two PCBs with OSHWHub. The DCDC board will be a double-layer board, and the PCIe board will be a 4-layer board.
DIY雷电3扩展坞，使用的贝尔金扩展坞拆出来的intel公模主板，刷入雷蛇CoreX固件。电源部分使用750W的CSPS电源，白金牌效率，自己设计嘉立创白嫖的PCB板，TI43060方案的12V输入20V输出模块，效率95，最大输出电流10A。
这里感谢知乎leaves大佬对雷电概念的讲解和固件分享
感谢霜秋大佬设计的CSPS取电板
感谢嘉立创对我们这种玩家的PCB支持
这一版的boost电路在layout上有一些问题，轻载输出有来自MLCC的杂音，我会在更改之后在嘉立创开源两片PCB，其中DCDC板为双层板，PCIE板为4层板a
Повторяем попытку...
