Toshiba has announced the launch of its new wireless power receiver IC, TC7764WBG, that will enable mobile devices to be charged wirelessly as fast as if they were connected to the charger through a cable.

The TC7764WBG is equipped with Qi V.1.1.2, the wireless low power charging standard defined by the Wireless Power Consortium (WPC), which includes a dedicated specification for smartphones and mobile accessories.

Toshiba has optimizing the circuit design of the TC7764WBG compared to its predecessor products, enabling maximum output power of 5W and maximum power conversion efficiency of 95 percent.

This will allow wireless charger makers utilizing the new IC to achieve performance as fast as that offered by cabled chargers.

The new IC integrates a protocol authentication circuit for power transfers, foreign object detection functions, under-voltage lockout (UVLO) and over voltage detection (OVLO) functions, as well as thermal shutdown function (TSD).

The IC is housed in a WCSP28 package measuring just 2.4mm by 3.67mm by 0.5mm.
