A common sensor requirement is to measure light. This may be for adjusting the brightness of a display or for instrumentation where accuracy is of importance and light levels could be very low. The light could be relatively constant or slowly changing, or it could be modulated at high speed. There are a number of […]

The circuit protection connection for wearables and the IoT
by JAMES COLBY, Littelfuse Circuit protection technologies and board layout strategies help promote safety, reliability and connectivity. There’s one down-side to wearable technology that is unlikely to show up in headlines about the IoT: Human bodies generate static electricity as they move. That static electricity can potentially harm the sensitive electronics that power IoT applications. […]
Infineon digitizes power for energy-efficient LEDs
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 CO 2 could be saved in Germany alone, equaling the emission of about seven million cars; in German office buildings, the electricity bill could be reduced by more […]

Driving High Power LEDs
High power LEDs, particularly “white” ones are becoming increasingly used in commercial products from cars and domestic lighting to street lighting and with efficiencies which can exceed that of compact fluorescent lamps (CFL). That efficiency is likely to improve as the technology develops but you must also pay attention to your drive circuitry, not simply […]
