GaN technology has matured to a point where it can challenge traditional silicon technology. Gallium nitride(GaN)-on-silicon low voltage power devices have enabled many new applications since commercial availability began in 2010. New markets, such as light detection and ranging (LiDAR), envelope tracking, and wireless power, emerged due to the superior switching speed of GaN. These new applications have helped develop a strong supply chain, low production costs, and an enviable reliability record. All of this provides adequate incentive for the more conservative design ...
Alex Lidow and his team of Michael de Rooij, David Reusch, and John Glaser gave an excellent technical tutorial this morning to a packed audience of Professional Engineers (PEs). The topic was a very timely ‘Maximizing GaN FET and IC performance: Not just a drop-in replacement of MOSFETs’.
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).
