Description

The P9243-GB-EVK Evaluation Board demonstrates the features of the P9243-GB 15W Wireless Power Transmitter (TX) with a fixed frequency. It is intended to evaluate the functionality and performance of the P9243-GB when combined with a Qi power receiver in a wireless charging system. The P9243-GB-EVK offers the flexibility to select parameters, such as Q-factor threshold, LED pattern, power loss FOD threshold, and external temperature sensing function. The printed circuit board (PCB) has four layers, and can be used with the user’s WPC-1.2.4 compliant receiver.The high-efficiency, turnkey reference design is supported by comprehensive digital resources to significantly expedite the design-in effort and enable rapid prototyping.The kit contents are P9243-GB evaluation board and Power Adaptor. WPD-USB-DONGLE is not included in the P9243-GB-EVK evaluation kit, and must be ordered separately.
