How to Design a USB-C Power Supply (5V–28V) in 3 Hours | Full Tutorial | EasyEDA
The video walks viewers through building a USB‑C power‑supply board that delivers 5 V to 28 V, using only a web browser and EasyEDA’s Pro edition. No local software installation is required; users create a new project, name schematics and PCB files, and set up a professional‑looking title block. Key steps include selecting a 28 V‑rated USB‑PD controller from LCSC, editing its schematic symbol for clearer pin placement, and adding high‑voltage capacitors, TVS diodes, and filtering components. The tutorial emphasizes using a 0.1 mm grid, copying existing net names to avoid errors, and configuring output voltage via three‑position switches with pull‑up resistors on the CFG pins. Notable details: the presenter saves every change, stores a custom symbol in a personal library, and deliberately places unfitted resistors for future experimentation, annotating them with notes. A simple table maps switch settings to output voltages (5 V, 9 V, 12 V, 20 V, 28 V), illustrating how configuration pins control the regulator. The approach demonstrates that a functional, high‑voltage USB‑PD supply can be designed, documented, and ready for PCB fabrication in under three hours, lowering the barrier for hobbyists and small‑team engineers to prototype power solutions quickly.
PCB Layout Finished 10x Faster with AI? Here’s How...
The video introduces Quilter, a startup applying artificial intelligence to the PCB layout stage of hardware design, and explains how its founders aim to shrink the traditionally slow layout process. Quilter deliberately avoids LLMs, treating layout as a geometry‑and‑physics problem solved...
