Toshiba Electronics Europe (TEE) has announced the launch of a wireless power receiver IC, TC7765WBG, and a transmitter IC, TB6865AFG Enhanced Version, as a 10-watt-class wireless power solution for smartphones, tablets and mobile accessories using the Qi Standard Low Power Specifications version 1.1, defined by the Wireless Power Consortium (WPC).
With increasing awareness of the use of wireless power supplies to charge portable devices, such as smartphones, tablets and their accessories, demand is growing for higher-power wireless charging systems that shorten charge times.
The new receiver IC, TC7765WBG, increases power by boosting the output voltage from 5V/1A to 7-12V/1A. The transmitter IC, TB6865AFG Enhanced Version, realizes a 10-watt- class wireless power solution based on a revised peripheral circuit configuration and new software.
The TC7765WBG’s built-in protocol authentication logic circuit for power supply control eliminates the need for set makers to develop software. The TB6865AFG Enhanced Version also supports the software necessary for the higher power supply operation, allowing makers to easily incorporate 10-watt-class solutions into their products. This advance will reduce development times for 10-watt-class wireless power supplies for manufacturers’ systems.
Sample shipments start from the end of this month, with mass production scheduled to start in June 2015.
