Hello, I am wanting to use this Wireless Power Transfer Rx Coil Module for a project; however, because of the limited information on the datasheet, I am hesitant. I am wanting to connect this to a buck/boost converter to allow for constant current. Any further information would be welcome in addition to the questions below.
Questions:
What does the WC_EN pin/pad do for the device?
Also, to clarify, do Vchar_IN and GND pads/pins act as V+ and ground?
Can this device be operated similar to most 3-terminal devices?
What is its efficiency?
Unfortunately we have very limited information on this part, we don’t even stock them at our warehouse. Your best bet for information would be to contact the manufacturer for more info, they may have more detailed datasheets available.

Did you ever get clarification on the voltage for the enable pin? Also, is there any guidance for transmitter module or one that is compatible? The one by TDK is nowhere to be found (according to octopart).
I found the WC_EN is not needed. I directly connected and LED strip on + and - and it worked.
Also I had an issue using a multiple voltage power supply on the transfer piece. I used a manually adjustable PSU and it worked great.
