LED drivers target automotive apps with wide programmable frequency operation, spread-spectrum clock
The TS19501 single-channel, dimmable LED driver targeting high-brightness automotive applications is well suited for virtually every automotive LED application: high and low beam headlights; daytime running lights; turn indicators; position indicator lights; fog lights; ATV and four-wheel drive high-brightness lamps. The IC is also offered in a version ideal for a wide range of non-automotive […]
Using energy harvesting to power wireless IoT nodes and wearables
Three elements are necessary to effectively implement energy harvesting (EH) into wireless IoT nodes, wearables and similar low-power applications. First, it a detailed power profile needs to be developed that considers active and sleep modes to produce a realistic estimate of the average power consumption. The power profile is used to size both the harvester […]
EN 50155-certified 60-W industrial/railway converter handles 4:1 input range
TRACO POWER’s new 60 W TEN 60WIR family of high-performance DC/DC converters offer an ultra-wide 4:1 input range in a 1 x 2” footprint. Standard models come pre-packaged with a heatsink extending the footprint to 1.60 x 2.00 x 1.00” for improved thermal performance. The TEN 60WIR family consists of 24 models with a choice […]
Energy harvesting devices and ambient energy availability
Various forms of ambient energy are available in most environments. Depending on the environment and the power needs of the device, common energy harvester choices include light harvesters, thermoelectric harvesters, and mechanical vibration harvesters. Each of these energy harvesting technologies can be optimized for maximum performance in a given environment. In the case of light […]
Next-generation shielding may absorb electromagnetic interference rather than reflect it
Engineers trying to shield RF-sensitive circuitry a few years from now may have the option of using material that absorbs RF energy rather than just reflecting it. So say researchers at Drexel University and the Korea Institute of Science and Technology. They are researching a class of material called MXenes, and more specifically, titanium carbonitride […]
Energy harvesting applications, architectures and the massive IoT
Wireless sensor nodes, wearables, trackers, and displays are typical devices that can be powered using energy harvesting (EH), also called ambient energy, energy scavenging, or power harvesting. The availability of ambient energy for harvesting varies depending on the location and environment where the device is used. Among the many possible sources of ambient energy, the […]
Dual-output railway quality supplies put out 250 W
ABSOPULSE Electronics has recently released the PFC 252R-HSA-F3 series dual-output railway quality power supplies with pure convection cooling. The 250W units employ active power factor correction (PFC) to convert a universal 95V to 264Vac input to two outputs. Output V1 provides any voltage 12V to 110Vdc/10A to 14A max; output V2 offers any voltage 5V […]
Capacitor assemblies excel at power supply filtering
Knowles Precision Devices, a division of Knowles Corporation, recently expanded its capacitor assembly offering with the release of its new SV series of capacitor assemblies for power supply filtering applications. The SV series is a vertically stacked ceramic capacitor, offering superior performance compared with aluminum or tantalum electrolytic capacitors, while also helping to reduce the overall circuit board […]
Compact, single-phase EMC block filter meet space and performance constraints
SCHURTER completes its portfolio of single-phase EMC filters with its FMBB EP series, launching a new generation of ultra-compact filters with high-performing attenuation. The new double-stage filter family is more powerful than typical filters, meeting the space constraints and performance requirements of today’s state-of-the-art electronic devices. Top-quality components, including right-sized film capacitors and chokes with […]
