NU1680 5W wireless receiver

Overview

An ultra-small 5W wireless charging receiver with two versions, namely pure Type-C version and dual USB version. It should be noted that the dual USB version cannot be plugged into Type-A and Type-C at the same time, and Type-C cannot be plugged in at the same time. Plug in another power supply and actually eliminate the USB interface to get a smaller size.

It should be noted that the coil should have an inductance of 15.8uH. If not, it can be replaced by a similar one (because Voda does not provide a calculation formula for the resonant capacitance and coil inductance). When used, the coil is welded to both ends of the 1206 inductor. Please do not directly solder a 15.8uH inductor to the inductor position of the 1206 package.

This project provides two versions of PCB panels that can pass JLC review.

It's time to test your eyesight
It's been a while since I posted a question that tests your eyesight. I'll post one today.
12V lithium battery, is there any suitable charging circuit recommended?
I recently had a project that used a 12V lithium battery. I would like to ask if you have a stable 12V lithium battery charging circuit solution? Thank you very much~ The lithium battery is 3 series a
