TI's wireless power technology 80% smaller than previous generation
Texas Instruments has introduced its next generation of wireless power technology which is 80% smaller than its previous receiver chip. The bq51013 receiver integrated circuit has been designed to enable the implementation of wireless charging in existing and new designs for portable consumer devices, such as smartphones, digital cameras and medical and industrial equipment.
The device combines voltage conditioning and full wireless power control in a 1.9 x 3mm WCSP package. According to TI, it supports up to 5W of output power, provides up to 93% efficient ac/dc power conversion and is the only IC required between the receiver coil and system.
Sami Kiriaki, senior vice president of TI's Power Management business, said: "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. Designers can use the bq51013 to quickly integrate wireless power into existing and new applications with minimal impact to overall solution size."
