Intel Ceases Work On Wireless Charging

For the last three years, Intel has been stoking demand for PCs ahead of the next big buying cycle with the promise that new machines will be totally wireless. “We carry around a lot of wires,” Kirk Skaugen, Intel’s senior PC exec said at Computex Taipei 2015. “We carry about six cables each for our phones, our tablets and our PCs. We want to get rid of all those cables.”

5 Industries That Are Actually Ripe for Disruption

The number one barrier to improving every electronic product – from smart wearables and laptops to handheld tools and electric cars – is battery technology. The current state-of-the-art in rechargeable batteries, Lithium Ion, has been around for 25 years. As tech goes, that’s pretty old. It’s time for something new, don’t you think?

WiGaN: Low Cost Differential-Mode Wireless Power Class-E Amplifier Using eGaN FETs

In this installment of WiGaN, a differential-mode class-E amplifier for 6.78 MHz loosely coupled resonant wireless power applications is presented. It uses the EPC2037 eGaN® FET which has a small (0.9 mm x 0.9 mm) footprint and can be driven directly with a logic gate. The amplifier is AirFuel™ Class 2 compatible, capable of delivery up to 6.5 W load power over an impedance range of 70j Ω.

What GaN circuits can do for wireless charging

In this short video, EPC's Alex Lidow explains why GaN FETs may make it possible to wirelessly charge a variety of vehicles, including flying drones. Wireless charging circuits employing GaN FETs work at 13.56 MHz, a switching frequency difficult to reach with ordinary silicon FETs. The GaN transistors used are also five to ten times smaller than silicon devices able to handle the same power levels.

Highlights from APEC 2016 – GaN, 48V POL, wireless charging and more!

Emerging applications such as 48V-to-point-of-load (POL), wireless power and USB Type-C had a lot of interest. Google joined the Open Compute Project a few weeks ago and proposed a computer server-rack architecture based on a 48V power-distribution bus to improve overall system efficiency. While the 48V bus has been around for a long time, the push (and challenge) is for high-efficiency 48V-to-POL voltage regulators. EPC showcased TI’s 48V-to-1V EVM which uses the LMG5200 GaN module (driver and FETs), announced at APEC last year, and a new TI analog controller (TPS53632G).
