How to design the coil for BQ51013??

In my project the most important part is size.

I already purchased your EVM kit.

It really works well.

I want to use whole system except for  the coil which is in receving part.

It should be less size then you have.

Where can get information for coil design?

    See Analog Application Journal Article “Designing a Qi-compliant receiver coil for wireless power systems”  3Q 2012—SLYT479.

    Receiver coil design can be difficult and you should expect to modify your coil design to meet performance requirements.  I would recommend separating out coil design from RX and TX debug.  Test the RX with a know good coil and test the coil with a know good RX.
