How to set the STWLC38 to 15W(EPP)

Hi,

I use the STWLC38 for wireless charging.

Just set the BPP VOUT to 9V, and other REG is in default value.

In test , the output current around 0.6A . (The chip emits a squealing sound)

If I want to set the Rx to 15W, which REG I need to set. 

And I have a question about the RX LDO configuration in datasheet。 There is no detailed explanation regarding the threshold. How should these registers be configured?

Thank you!
