P9242-R Transmitter Evaluation Board Transmitter Coil
P9221-R-EVK
Description
The P9221-R-EVK Mass-Market Evaluation Board demonstrates
the features and performance of the P9221-R 15W Wireless
Power Receiver (R
X
). It is intended to evaluate the functionality
and performance of P9221-R. The P9221-R-EVK offers the
flexibility to program parameters, such as output voltage, over
current limit threshold, and external temperature sensing function.
It also enables tuning the Foreign Object Detection (FOD) by
connecting the center tap of the on-board resistor dividers to each
of these pins. The printed circuit board (PCB) has four layers. The
P9221-R Evaluation Board is designed to function with the
P9242-R Transmitter Evaluation Board, which is ordered sep-
arately. It can also be used with the user’s WPC-1.2.2 compliant
transmitter.
The high-efficiency, turnkey reference design is supported by
comprehensive online, digital resources to significantly expedite
design-in effort and enable rapid prototyping. The total active area
is optimized to 28 mm x 15 mm.
