Weatherproof […]
World’s first 100 mW deep-UV LED
LG Innotek says it has developed the world’s first 100-mW UV-C LED. The UV-C LED emits ultraviolet light with short wavelengths ranging between 200 – 280 nm and is also called deep UV. It is used in sterilizing and hardening devices with its ability to destroy bacterial DNA and cause chemical reactions with special materials. […]
Natural-spectrum LEDs get RG-1 Eye Safety certification
Seoul Semiconductor announced that SunLike Series LEDs, which implement light that closely matches the spectrum of natural sunlight, received an RG-1 Eye Safety certification based on the safety of its light source and was recognized for the highest level of safety among 25W COB type LED. Eye Safety certification is a rating based on safety […]
Longer battery life for hearables and wearables
Single-inductor, multiple-output circuitry can provide the kind of high conversion efficiency necessary for super-small consumer electronics. Cary Delano, Reno Rossetti | Maxim Integrated When you’re designing hearables and wearables, user experience dictates that long battery life is a key requirement. Nobody wants to stop and recharge the batteries on their earbuds during a long walk […]
The difference between vehicular and non-vehicular LED drivers
There are numerous features in the electronics that power vehicular LEDs that you won’t find in other LED applications. Jatin Thaker, Dave Strycharz | NXP Automotive The automotive market is quickly moving away from traditional incandescent lighting towards more intelligent systems that promote reduced energy use, safety, and individualization options that boost brand recognition. Automotive […]
Compact LED drivers put out 24 W with 20 W/in.3 power density
Seoul Semiconductor has developed an ultra-compact LED driver series with a power density 5X higher than conventional LED drivers. Based on Seoul Semiconductor’s patented Acrich technology, the MicroDriver Series delivers more than 24W of output power with a power density of 20W/cubic inch cubic inch, compared to existing drivers at 3-5W/cubic inch. Measuring just 1.5” […]
Wireless-charging IC juices up smartphones and tablets
The relative convenience of performing multiple tasks on your phone and tablet is often offset by the frustration of having to charge your devices sometimes multiple times a day. Consumer applications accounted for more than 55 percent of the overall wireless charging market share in 2016, according to Global Market Insights. Major smartphone manufacturers, said […]
Programmable power supply measures power consumption of embedded processors
STMicroelectronics’ STM32 Power Shield enables developers to check the power consumption of their embedded designs accurately, using the same hardware chosen by EEMBC as the new reference platform for the IoTConnect and ULPMark™ (Energy Monitor V2.0) benchmarking frameworks. Compatible with STM32 Nucleo development boards, the STM32 Power Shield (X-NUCLEO-LPM01A) dynamically monitors the current under various operating […]
