Energous launches GaN-based wireless solution for charging electronic devices with up to 10W
Energous Corp of San Jose, CA, USA (a developer of WattUp wire-free RF charging technology that provides over-the-air power-at-a-distance) has launched a high-power Near Field WattUp charging solution for electronic devices such as smartphones, tablets, smart speakers, game controllers, drones etc.
The new high-power Near Field WattUp charging solution includes: a GaN-based 5-10W RF receiver IC; a GaN-based 10-15W RF power amplifier (PA); allowance for full 2D/planar movement; support for 90˚ charging angles (sideways charging); a smaller receiver (RX) size, superior accomodation of metal and other foreign objects; and PA integration into the overall system, leading to a lowered bill-of-materials (BOM) cost.
The new transmitter reference design can charge devices with up to 10W of energy, significantly increasing the amount of power delivered to receiving devices and eliminating connectors and charging contacts for a much wider variety of devices.
“We continue to grow our WattUp wire-free charging ecosystem with reference design solutions that will support the technology adoption in an even broader range of customer products,” says president & CEO Stephen Rizzone. “Extending the high-power capabilities of Near Field WattUp charging enables many different types of devices to be charged from multiple transmitter options. By continuing to expand the portfolio of reference designs available to customers, we are able to support increasing requests from our various partners for additional options and power levels,” he adds.
“With a catalog of reference designs ranging from high-power, quick-charging, low-power, small-form-factor, Mid Field and Far Field power-at-a-distance, customers now have the ability to meet virtually all of their wireless charging requirements from a single source,” comments Mark Tyndall, senior VP of corporate development & strategy at Dialog.
“These first GaN-based solutions for our WattUp wire-free charging technology support higher power and improved charging flexibility,” says founder & chief technology officer Michael Leabman. “Our ability to develop multiple components within the WattUp ecosystem allows us to innovate based on our customer needs,” he adds.
