Intel energizes wireless charging effort

September 05, 2012 // By Peter Clarke
Intel Corp., has selected mixed-signal fabless chip company Integrated Device Technology Inc., to make transmitter and receiver ICs to implement Intel's resonant wireless energy transfer technology.

Intel (Santa Clara, California) is pushing hard to bring the technology to market to improve the attractiveness of mobile offerings based on its processors such as Intel-based ultrabooks and smartphones. Intel has been developing resonant wireless charging since before October 2008.

IDT (San Jose, California) said it plans to be able to provide samples the resonance receiver IC by the end of 2012 and the year, and of the transmitter IC sometime in the first half of 2013. Intel and IDT also plan to deliver resonant wireless charging reference designs for use in Ultrabooks, PCs, smartphones, and standalone chargers.

Wireless charging over distances of a few millimeters or centimeters using magnetic induction has been seen as a promising application area for a number of years but has been difficult to find an efficient means of energy transfer and consensus on standards has been slow to build.

"Our extensive experience in developing the innovative and highly integrated IDTP9030 transmitter and multi-mode IDTP9020 receiver has given IDT a proven leadership position in the wireless power market,” said Arman Naghavi, vice president and general manager of the analog and power division at IDT, in a statement.

"We think the ability to have a wire-free charging experience with a broad ecosystem of devices like keyboards, mice, storage devices, cameras and smartphones will be realized in the near future," said Gary Huang, director of PC growth and innovation at Intel, in the same statement.
