bq51020EVM (5-W WPC) Integrated Wireless Receiver
The bq51020EVM-520 (PWR520-002) wireless power receiver evaluation kit (EVM) from TI 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 bq51020 IC, a secondary-side receiver device for wireless
power transfer in portable applications. The bq51020 device is a fully-contained, wireless power receiver
capable of operating in WPC v1.1 protocol which allows a wireless power system to deliver up to 5 W to
the system when used with a Qi inductive transmitter. The bq51020 device provides a single device power
conversion (rectification and regulation) as well as the digital control and communication for WPC
specification. The kit enables designers to speed up the development of their end-applications.
