Toshiba Launches 10 Watt Class Speed Wireless Power Solution

January 6, 2015

TOKYO–Toshiba Corporation (TOKYO: 6502) today announced the launch of a wireless power receiver IC, "TC7765WBG", and a transmitter IC, "TB6865AFG Enhanced Version", as a 10-watt-class speed wireless power solution for smartphones and tablets using the Qi Standard[1] Low Power Specifications version 1.1, defined by the Wireless Power Consortium (WPC).

Sample shipments start from the end of this month, with mass production scheduled to start in June 2015.
 

With increasing awareness of use of wireless power supply 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 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 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 supply for manufacturers’ systems.

Key Features of New Products

  • Input voltage = 19V
  • Output voltage =12V (maximum), Output power = 12W (maximum)
  • WPC Qi standard LP v1.1
  • Using the WPC Qi standard LP A10 type coil (transmitter side)

Applications

Smartphone, tablet, mobile accessory
