IDT has been allowed to reveal it is providing silicon for Ikea’s forthcoming range of wireless charging furniture.
The firm’s P9030 magnetic induction transmitters are embedded in products including side tables and lamps.
The transmitter complies with the Wireless Power Consortium’s Qi standard, delivering 5W. IDT also does chips for the Power Matters Alliance and Alliance for Wireless Power systems.
Ikea will not only be selling furniture that include charging, but chargers for customers to insert into holes of their own making – compatible with the WPC1.1 standard, the one pictured is called Jyssen and fits though a 77mm hole, popping up to reveal a USB connector when wired charging (2A) is required. With Ikea’s usual cunning, it is shaped to allow mouse and keyboard cables to share its hole. Ikea has not revealed stand-by or transfer efficiency figures which, for all wireless charging types, have been comparing poorly with wired charging.
The cross logo allows proper phone-charger alignment to be established, which is needed for maximum power transfer.
