bq51010BEVM-764 Evaluation Module (WCSP Package)
The bq51010BEVM-764 (EVM) wireless power receiver evaluation kit from TI is a high-performance, easy-
to-use development kit for the design of wireless power solutions. The EVM helps designers to evaluate
the operation and performance of the bq51010B, 7-V power supply for wireless power transfer. The
bq51010B devices provide AC/DC power conversion and regulation while integrating the digital control
required to comply with the Qi-communication protocol. The kit speeds up the development of end-use
applications.
