10-Watt class, wireless power chipset

January 06, 2015 // By Graham Prophet
Toshiba Electronics Europe has a wireless power receiver IC, TC7765WBG, and a transmitter IC, TB6865AFG Enhanced Version, that together comprise a 10-W-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).

The receiver IC, TC7765WBG, increases power by boosting the output voltage from 5V/1A to 7-12V/1A. The transmitter IC, TB6865AFG Enhanced Version, realises a 10-W-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 incorporate 10-W-class solutions into their products in shorter design time.
