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,
