Toshiba Announces Qi-certified 15W Wireless Power Transmitter System

Connected to a microcontroller, “TC7718FTG” realizes a wireless power transmitter system compliant with Qi standard. Toshiba’s original cutting-edge CD-0.13 process realizes a small package and high efficiency, making system integration easy while securing a small footprint. A 15W wireless transmitter formed with the new IC will recharge devices quickly, at a rate equal to or shorter than wired chargers. The IC is suitable for use in wide range of applications including mobile devices, such as smartphones and tablets, and industrial devices.

A wireless power transmitter system using “TC7718FTG” is compatible with a 5W receiver system using Toshiba’s 5W receiver IC “TC7764WBG”, and a 10W receiver system using its 10W receiver IC “TC7765WBG”, both of which are in mass production. In combination with a 15W receiver IC “TC7766WBG” already certified as the Qi v1.2 EPP compliant, the wireless power system can receive up to 15W.
Toshiba is the industry’s first^[3] company to provide Qi v1.2 EPP-certified products for both 15W wireless power transmitters and receivers.
