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.
