Greetings Chad

This message may not be directly relevant but I would appreciate if you would guide me with a solution if possible. I am looking to create a wirelessly chargeable power bank that is both capable of being charged and also capable of charging wirelessly. The opportunity is t understand how small the power bank can be in both capacity and size to manage both tasks to charge a 2000 mAh device.

Thank you

Deepak Lalvani

Hey Chad,

Do you use an autorouter, considering all your traces are diagonal? Also, you might want to look into board layout guidelines for switching converters. I guess the board will work as you designed it, but performance will not be optimal this way, probably more switching noise (both on the outputs and radiated) than necessary. Especially routing GND and placement of input- and output caps can help a lot. Just to be sure: this is meant as positive feedback, maybe it helps in troubleshooting later on.

Hi Chad,

You do good board design work.

I agree with the keep it simple approach. I think most people just need certain pins available to attach to their normal prototype board. I know for my own uses, once the design works, the CAD work is usually fast and clean enough to go right to a PC board, so having a prototyping area with the board format is usually a wasted effort.

Thanks for the update,

DAB
