Description
The IDT P9221-R-EVK Mass-Market (MM) Evaluation Board dem-
onstrates the features and performance of the P9221-R 15W
Wireless Power Receiver (Rx). The P9221-R-EVK offers the flexi-
bility to program parameters, such as the output voltage, over-
current limit threshold, and external temperature sensing function.
It also allows tuning the Foreign Object Detection (FOD) feature by
varying values in the resistor divider connected to the VOSET/
Q-Fact pin.
The P9221-R-EVK MM Evaluation Board is designed to function as
the receiver in a wireless power transfer system using IDT’s P9242-
R-EVK MM Evaluation Board as the power transmitter. The P9242-
R-EVK is ordered separately. The P9221-R-EVK can also be used
with the user’s WPC-1.2 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 printed circuit
board (PCB) has four layers. The total active area is optimized to
28mm x 15mm.
