New crystal structure triples output power of GaN transistors, expands radar observation range
Fujitsu and Fujitsu Laboratories have succeeded in developing a transistor that can provide both high current and high voltage in gallium-nitride (GaN) high electron mobility transistors (HEMT), effectively tripling the output power of transistors used for transmitters in the microwave band. Fujitsu’s crystal structure improves operating voltage by dispersing the applied voltage to the transistor, and […]
ICs comply with USB Power Delivery 3.0 standards for fast charging of smartphones, tablets, and notebooks
Power Integrations announced that a range of adapter designs based on Power Integrations’ InnoSwitch3-Pro and InnoSwitch3-CP ICs have achieved compliance with USB Power Delivery (PD) 3.0 standards. During a recent workshop in Portland, Oregon, nine adapter designs featuring InnoSwitch3 devices – including several designs submitted by leading power-supply manufacturers – successfully completed USB PD 3.0 […]

Grid links get more compact thanks to gallium nitride
Serkan Dusmez from Texas Instruments recently recorded a short video with us on a gallium-nitride based grid link. It is a three-phase, three level bidirectional grid tight inverter developed jointly by Texas Instruments and Siemens. It includes 600-V GaN TI drivers that incorporate smart features like over voltage protection and over temperature protection in a […]
TI solar SiC MOSFET gate drivers make for smaller inverters
Nagarajan Sridhar from Texas Instruments recently filmed a video with us covering a demo of a solar panel inverter that uses Texas Instruments silicon carbide MOSFET gate drivers. He points out that the switching frequency of silicon carbide far exceeds the capability of that available through silicon IGBTs or MOSFETs. The demo circuit is a […]
How eGaN transistor technology improves Lidar performance
Alex Lidow from EPC recently filmed a video with us covering Lidar, a hot subject right now for autonomous vehicles. One of the biggest applications for eGaN is driving these lasers. The reason is that automakers want to see a long distance with a high degree of accuracy. To do that, the laser in a […]
Graphics-intensive apps get more juice from GaN dc/dc converters
Alex Lidow from EPC recently did a short video with us covering a brand new GaN-DC/DC converter that’s super small and efficient. Lidow says EPC has been working to improve GaN-based dc/dc conversion for about eight years. They had to overcome a lot of barriers to do so because when they first started, there were […]
