When I started working with eGaN FETs almost six years ago, I had no idea what to expect from this technology. We had our first preliminary datasheet and even though I had no idea what to expect, it was obvious that, on paper, these devices were much better than your typical MOSFETs – already beyond the theoretical

Infineon digitizes power for energy-efficient LEDs

ICL8105 is a digitally-configurable flyback controller

Every fifth kilowatt hour of electricity around the world is used for artificial light. LED technology, however, is making significant savings possible. About 13 million tons of CO2 could be saved in Germany alone, equaling the emission of about seven million cars; in German office buildings, the electricity
