Semtech Announces New LinkCharge® 40 for 40W Wireless Charging

LinkCharge 40 among the first of its kind to bring wireless charging capabilities to high power devices

CAMARILLO, Calif., Oct. 16, 2018 – Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced the release of a new LinkCharge® reference design and evaluation boards for 40 watt wireless charging – one of the first of its kind for higher powered devices. LinkCharge 40 brings wireless charging capabilities to high power devices such as battery powered tools, computer tablets and laptops, mid-size household appliances including kitchen equipment and automatic vacuum cleaners.

“As one of the first 40W wireless charging platforms, we expect the LinkCharge 40 to be the disruptive solution enabling wireless charging functionality for an entirely new range of higher power products,” said Francois Ricodeau, Sr. Product Line Manager for Semtech’s Wireless and Sensing Products Group. “Semtech’s Power Products continue to drive the innovation necessary to create change in ease of power management and efficiency in electrical usage.”

The new LinkCharge 40 implements Semtech’s new patent-pending Foreign Object Detection (FOD) system to safely stop power transfer in the event an unintended object is placed on the power transmitter, with or without presence of a compatible receiver. In order to keep the equipment cool during charging, the DC-DC efficiency of the platform has been measured up to 80% at a 20W half load and up to 85% efficient for a full 40W load.

The entire chipset for both transmit and receive is available for $8.75 in quantities of 10,000 units.

LinkCharge 40 EVBs are available at Mouser and Digikey, or by contacting your local sales office. Learn more about LinkCharge 40 on our website.
