10W Wireless Charger(TX, Automotive)

We want to make 10W TX wireless charger(automotive).

But NXP has 15w(mwct101xA) and 5w(mwct100xA). Then 101xA is a proper solution for 10W solution?

I guess 15W solution itself can give 10W to RX only if RX requests 10W to TX.


But I wonder if there is something for reducing BOM, 


If yes, what needs to be modified on both hw & sw sides?

For example, WCT-15WTXAuto uses a Digital buck/boost. The Rail voltage  is up to 25V approximately.

if a 10W Solution, such a high rail voltage would not be required. So is the digital duck/boost able to be replaced with cheaper one( max 1x Voltage range)?


On SW side, there will be some parameters related with voltage or  power limit. I wonder i fthese parameter also should be modified.


Thanks & BR,
