Project Description
The USB-C Li-Ion Charging PCB is a compact circuit board that charges a 3.7V Li-Ion cell via USB-C and provides a stable 9V output using an efficient boost converter. The design is thermally optimized and has a minimal footprint.
The circuit board is developed in EasyEDA and includes features such as ESD protection, power path management and current limiting. This makes the board extremely suitable for integration in small embedded systems or as part of a modular electronic system.
The project is a fine example of efficient power electronics, clean PCB design and attention to reliability in compact applications. Perfect for DIY kits, wearables or embedded projects.
