Power receiver and transmitter combine for 10W wireless power solution
16 January 2015 
Toshiba Electronics Europe has launched a wireless power receiver IC, the TC7765WBG, and a transmitter IC, the TB6865AFG Enhanced Version, as a 10W 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). Demand for wireless power supplies to charge portable devices, such as smartphones, tablets and their accessories, fuels demand for higher-power wireless charging systems that shorten charge times. The TC7765WBG increases power by boosting the output voltage from 5V/1A to 7 to 12V/1A. The TB6865AFG Enhanced Version, realises a 10W-class wireless power system 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. This will reduce development times for 10W-class wireless power supplies predicts the company. Sample shipments start the end of this month; mass production is scheduled to start in June.
