TOKYO--()--Toshiba Corporation's (TOKYO:6502) Storage & Electronic Devices Solutions Company today announced that a wireless power transmitter system using its “TC7718FTG” 15W wireless power transmitter IC has been certified as Qi[1] v1.2 EPP (Extended Power Profile) compliant by the Wireless Power Consortium (WPC). The system adopts MP-A2[2], which allows a simple system configuration, and is the industry’s first[3] Qi-certified MP-A2 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.
