TI intros industry’s smallest wireless power receiver chip

USA: Texas Instruments Inc. (TI) recently introduced its next generation of wireless power technology, which is 80-percent smaller than TI’s previous receiver chip.

The tiny, highly integrated device makes it easy for designers to implement wireless charging in their existing and new designs for portable consumer devices, such as smart phones, gaming systems, digital cameras, and medical and industrial equipment.

The bq51013 receiver integrated circuit (IC) combines voltage conditioning and full wireless power control in a small 1.9-mm x 3-mm WCSP package. The new circuit supports up to 5 W of output power, provides up to 94-percent efficient AC/DC power conversion and is the only IC required between the receiver coil and system.

“Smartphone and consumer electronics manufacturers are demanding wireless power, and TI is well positioned to help our customers drive widespread adoption of this technology that makes life easier for people on the go to charge their devices,” said Sami Kiriaki, senior vice president over TI’s Power Management business.

“Designers can use the bq51013 to quickly integrate wireless power into existing and new applications with minimal impact to overall solution size.”
