Most consumer devices that transfer power over wireless links follow the Qi standard. The construction of these power transfer systems is simpler thanks to the availability of new reference designs. Contributed by IDT Inc. Examine the wireless charging setup used in the passenger compartment of most vehicles and you are likely to find a system […]
High-power-density POL converters target AI, 5G, IoT, enterprise apps
TDK Corporation announces the new series of µPOL DC-DC converters, the industry’s most compact and highest power density point-of-load solutions for applications such as big data, machine learning, artificial intelligence (AI), 5G cells, IoT and computing enterprise. Rather than using side by side discrete integrated circuit (IC) and discrete inductor (L) the new FS series […]
Energy efficiency, smart lighting, and the IoT
Sure, smart lighting will save energy, but they’ll also be the backbone of systems that can help minimize mini-catastrophes. CEES LINKS, Qorvo THE IoT (internet of things) INCLUDES a rich offering of energy efficiency benefits. Smart lighting is, of course, one of the most common elements of any IoT energy efficiency discussion. Lighting is a […]
Evaluating options for USB Type-C connections
Port controllers, transceivers, and special dc/dc converters now simplify the task of adding USB Type-C functions. DANIEL LEIH, MICROCHIP TECHNOLOGY INC. CONSIDER THE VIRTUES of the USB-C connector. In addition to its 10 Gbit/sec (Gbps) bandwidth and Alt Mode video capabilities, two attributes, in particular, make this form factor incredibly valuable: a reversible plug and […]
Energy-efficient RECOM power supply series now at Rutronik
RECOM’s latest 15W and 20W AC/DC power supplies, the RAC15-K and RAC20-K, are designed for low power IoT and household applications. Based on the footprint of the compact RAC10-K modules, these new modules feature high-efficiency over a wide load range and minimal standby power consumption. The RAC15-K and RAC20-K Series are PCB-mount AC/DC modules with ultra-low energy losses especially in light load conditions. […]
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 […]
