描述
The P9235A-RB-EVK Evaluation Board demonstrates the features of the P9235A-RB 5W Wireless Power Transmitter (TX). It is intended to evaluate the functionality and performance of the P9235A-RB when combined with a power receiver in a wireless charging system. The P9235A-RB-EVK offers the flexibility to select parameters, such as the over-current limit threshold, LED pattern, and external temperature sensing function using a graphical user interface (GUI). The printed circuit board (PCB) has four layers.
The P9235A-RB Evaluation Board is designed to function with the P9225-R Receiver Evaluation Board, which is ordered separately. It can also be used with the user’s WPC-1.2.4 compliant receiver.
The high-efficiency, turnkey reference design is supported by comprehensive online digital resources to significantly expedite the design-in effort and enable rapid prototyping. The total active area is optimized to 21mm x 21mm.

Wireless power transfer uses an air-core transformer with separate transmitter and receiver coils, making accurate performance modeling difficult due to low magnetic coupling and increased losses. This paper addresses simulation challenges and describes methods to approximate circuit behavior. It demonstrates best practices for tuning Qi and PMA inductive resonance circuits to maximize charging efficiency for mobile devices.
