The bq51221EVM-520 (PWR520-001) wireless power receiver evaluation kit (EVM) from Texas Instruments is a high performance, easy-to-use development kit for the design of wireless power solutions. It helps designers to evaluate the operation and performance of the bq51221 IC, a secondary-side receiver device for wireless power transfer in portable applications. The bq51221 device is a fully contained wireless power receiver capable of operating in both the WPC and PMA protocols which enables a system to not be confined to a one standard. The bq51221 provides a single stage power conversion while integrating the digital control and communication. The bq51221 complies with the WPC v1.1 and PMA communication protocol. The kit enables designers to speed up the development of their end-applications.
