Toshiba Launches Qi Compliant Wireless Power Receiver IC with Low Heat Generation

Toshiba Corporation (TOKYO:6502) today announced the launch of “TC7761WBG”, a wireless power receiver IC that complies with Qi Standard1 Low Power Specifications version1.1, defined by the Wireless Power Consortium (WPC). The IC will be used in wireless power supply applications, such as smartphones and mobile accessories. Mass production shipments start today.
ICs used in mobile applications including smartphones, are required to generate heat at low level, to prevent overheating. The “TC7761WBG” is fabricated with a combined CMOS-DMOS wafer process that cuts heat generation to 70% that of an equivalent product2 while achieving 95% power conversion efficiency. The IC’s built-in protocol authentication circuit eliminates the need for an external microcontroller, contributing to simplification of the system.
