Can operate at 15 watts

Toshiba America Electronic Components (TEAC) has come up with what it claims is the first single-chip wireless power receiver that can operate at 15 watts and is compliant with the wireless charging Qi v1.2, standard.

The receiver, which has the catchy title TC7766WBG, triples the amount of power that can be received without increasing the chip's size.

In a press statement, Tosh said that this extra juice enables wireless power for subsequent charging of smartphones, tablets and handheld devices at speeds comparable to or, in some cases, faster than conventional wired chargers.

The new 15W receiver includes all the functions needed to construct a standalone wireless power transfer RX system, TEAC said.

The receiver is compatible with Toshiba's current TB6865AFG 5W transmitter and its upcoming 15W TX IC, which also complies with the Qi v1.2 standard.

To handling 15W maximum output power, the RX receiver can handle a maximum output current of 1.7 amps and output voltage range of 5 to 14 volts.

It also has the new Qi Foreign Object Detection functions, which keeps metal objects near a charging device from receiving the electrical voltage.

The receiver is housed in a WCSP28 package that is 2.4mm x 3.67mm x 0.5mm in size.

Samples of the TC7766WBG wireless power receiver IC will be available by the end of 2015, with mass production expected to begin in spring 2016.
