Compact PMICs target consumer electronics with hot-plug capabilities
With a pair of feature-rich, high-performance and scalable power-management ICs (PMICs) from Maxim Integrated Products, Inc., designers of mobile systems can now maximize performance per watt while increasing system efficiency for computationally intensive deep-learning systems on chip (SoCs), FPGAs and application processors. The MAX77714 and MAX77752 address a broad spectrum of applications ranging from augmented reality/virtual reality (AR/VR), gaming, […]
5-W ac/dc modules handle wide mains voltages up to 480 Vac
RECOM has announced the global release of its exclusive 5W AC/DC converter, the RAC05-K/480 series, which accepts input voltages of up to 480VAC. They are also OVCIII rated with a 6kV surge protection, and operate reliably at industrial temperature ranges. This series is ideally suited for housekeeping operations in Industry 4.0, IoT and smart process […]
Halt and catch fire: The perils of cheap PoE
Dave Jeskey tells an interesting story about what happened when an LED lighting company operated a few of its products in a test chamber. The RJ45 plugs, used for making a connection to a Power over Ethernet cable, melted. The RJ45 plugs came from Sentinel Connector Systems where Jeskey is director of sales and marketing. […]
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 […]
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 […]
Website covers smart building controls and systems
Cortet by CEL announces a new online resource for manufacturers, integrators, installers and reseller of lighting systems, luminaires, lamps and control/management systems for industrial and office facilities, warehouses, and other large facilities. “Businesses and manufacturers looking to expand their product lines within the Smart Building Technology space face a fractured and disorganized cornucopia of suppliers […]
Energy processing units reduce dynamic switching, static leakage power components
Sonics, Inc., introduced ICE-P3, the IP industry’s first product to automate implementation of dynamic voltage and frequency scaling (DVFS). ICE-P3 is the newest member of the ICE-Grain Family of Energy Processing Units (EPU) that identifies, sequences, and controls power state transitions in hardware up to 500X faster than conventional software-based approaches. ICE-P3 includes all of the capabilities […]
Prototype, screen-printed, flexible and stretchable batteries for future ready-to-wearables
Charging — let alone recharging — a wearable is a significant challenge. Conventional recharging technologies don’t necessarily translate well to a piece of clothing that will literally go through the ringer in terms of stretching. But now Nanoengineers at the University of California San Diego have developed the first printed battery that is flexible, stretchable and […]
New heart rate sensor claims to cut power consumption of fitness watches
It’s said that nearly 80% of the battery power in smartwatches goes to running the heart-rate monitor. But a new generation of photodiodes able to function as heart-rate sensors consumes five times less energy than the devices now found in smartwatches. The new photodiodes were developed by a Swiss startup called ActLight in conjunction with […]
