Toshiba unveils wireless power receiver IC for quick charging

Toshiba Corporation is launching the TC7763WBG, a wireless power receiver IC for mobile equipment that is compatible with the Qi1 standard defined by the Wireless Power Consortium (WPC).
The international standard for inductive electrical power transfer over distances of up to 4 cm, defined by the Wireless Power Consortium.
The device is suited for use in smartphones and mobile accessories. The IC realises a charging time equivalent to charging with a cable. Mass production shipments has already started.
Wireless charging allows adoption of an insulated case free of exposed charging ports, an advantage of that is stimulating demand for waterproof portable products, such as smartphones and wireless video game controllers. High power transmission is also required for wireless chargers to reduce charging time.
The TC7763WBG adopts optimised circuit design to increase maximum output power to 5 Watts, comparable with a cable, enhancing applicability.
Toshiba is expanding its line-up of wireless power receiver IC.
Key Features
Maximum 5-watt output power
95 percent maximum power conversion efficiency
Integrates protocol authentication circuit for power transfers
Supports foreign object detection (FOD) functions
Adopts compatible pin assignments with TC7761WBG, which supports maximum 3.5 Watts, allowing replacement without any need to change PCB design
