BQ51013BEVM-764 WPC 1.1 Compatible Fully Integrated Wireless Power Receiver IC Evaluation Module

I am unable to find the datasheet of the coil being used. Also can someone point me to the design instruction and coil selection guide. By this I mean how to select which coil etc.

760308103202 WPCC datasheet

I am not quite sure if that is exactly what you are looking for, but check out the following documentation from the WPC:

Please let me know if we there is anything else you need to know.

Many thanks for the reply sir. I received an email regarding the supply of additional coils and was wondering if they are useful to me. In that respect I was looking into how I could modify the receiver so that I could have a larger surface area because I am having some issues in my physical design which cause misalignment of the two coils. I will document my findings of course.

I was also wondering what the various leds on the Wireless Power Demo kit do? I PDF in the documents sections are for an older revision I think. The buzzer is missing and the LED D7 is no where to be found.

Thanks again,

If you send me the link for the PDF, I will have a look at it.

You also may want to check the content side of the Wireless Power Group page for some more data and information.

Hope this helps.

I was referring to this link :Wireless Pwr Transmitter Eval Board

It is obviously not what was in the kit. Can you help me with:

1. Documentation for the Kit. I got the link for the USER GUIDE and am referring to the documents in the contents section. Updated documents anywhere for TX board and RX board?

2. At the RX end, What are the the coils I can use? I understand that the one being used is a 12uH and if I use any other value I will have to change the resonance circuit caps. I want to know if there is a design guide for this kind of stuff. I can probably muster the modifications to the circuit since the components are 0603. I am thinking of changing the coil because a) I want to see what performance variation I can get b) because element14 say we can have to coils for free so why not try to experiment.

Many many thanks in advance.

The user guide for the wireless power demo kit has all the links for the EVM boards printed in it. For the receiver EVM, the receiver chip, the transmitter EVM, the transmitter chip. The user guide for the receiver EVM also list, in its BOM, the coils with are guaranteed to work with it.
