QI - Wireless Power receiver MWPR1516

[olivier_ctm]

Hello,

I already designed the transmitter part of my wireless charger but i have some questions about the MWPR1516 wireless charging IC wich is the NXP component for the receiver part..

First, is it the only receiver available from NXP ? I didn't find others.

Second, what is efficiency of this device ? There are no courbs (efficiency vs output load for some Vout).

Many thanks for your help.

Best regards

Olivier

Hello Olivier,

yes, the WPR1516 is our only one wireless charging receiver IC. Please refer to this link. 

Unfortunately we do not have the separate efficiency values for the WPR1516. Generally it is possible to achieve efficiency of the whole system above 60%. Please see the table below. The WPR1500-LDO EVB contains the WPR1516 IC.

With Best Regards,

Jozef
