TI公司的bq51013是用于手提应用的无线电源传输的接收器,AC/DC效率达93%,全同步整流器, WPC v1.0兼容的通信控制,最大输入功率20W,主要用于WPC兼容的接收器,手机和智能手机,数码相机,手提媒体播放器(PMP)和手持设备.本文介绍了bq51013主要特性, 方框图, 无线电源联盟(WPC或Qi)电感电源系统框图以及无线电源接收器和电源系统框, bq51013EVM-725评估模块电路图和材料清单(BOM), 元件布局图.

The bq51013 is an advanced, integrated, receiver IC for wireless power transfer in portable applications. The device provides the AC/DC power conversion while integrating the digital control required to comply with the Qi v1.0 communication protocol. Together with the bq500110 transmitter controller, the bq51013 enables a complete contact-less power transfer system for a wireless power supply solution. By utilizing near-field inductive power transfer, the receiver coil embedded in the portable device receives the power transmitted by the transmitter coil via mutually coupled inductors. The AC signal from the receiver coil is then rectified and regulated to be used as a power supply for down-system electronics.
