Texas Instruments Inc. rolls its next generation of wireless power technology, which is 80 percent smaller than the company's previous receiver chip. According to TI, the small, highly integrated device makes it easy for designers to implement wireless charging in their existing and new designs for portable consumer devices, such as smartphones, gaming systems, digital cameras and medical and industrial equipment.

TI's bq51013 receiver 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 5W of output power and provides up to 93 percent efficient AC/DC power conversion. TI boasts that the bq51013 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 of TI's power management business.
