Dear TI employees：

I just buy the bq500412evm and bq51013bEVM. I also want to design my own project. Can you tell how to do the coil calculation and how to choose the coil? Thank you.

Best regards,

Yang Fan

    Hello Yang Fan
    Coil design can be difficult, I would recommend using off the shelf coils that are used on the EVM to start your evaluation. We have smaller coils that are used on TX ref designs TIDA-00762 and RX ref designs TIDA-00318. Also see FAQ section under articles.
