New bricks extend intermediate-bus options Product News 7/1/2004 Post a comment Celestica's HUS42-096 half-brick and QUS20-120-NVDR quarter-brick DC/DC converters, part of the company's IBC series, are designed to optimize intermediate-bus architectures. The 460-watt HUS42-096 has a 5:1 input/output voltage ratio (the first half-brick of its kind, according to the company), and thus will provide 7 to 11 volts (often considered the "sweetspot" for highest overall system efficiency) from a 36- to 55-volt input. The QUS20-120-NVDR quarter-brick is the vertical-mount version of
Real-time video capture creates memory power concerns News & Analysis 7/1/2004 Post a comment As carriers and content providers usher in the wireless lifestyle, handsets will undergo an unprecedented transformation. Video capture and 3-D gaming at VGA resolution and 6-megapixel image capture will all become commonplace in the next two years. All will consumer power.
Charge pumps offer low-power backlighting News & Analysis 7/1/2004 Post a comment One drawback to the new suite of features being added to mobile phones is the higher current consumption for display backlighting. Color LCDs require white light to provide backlighting for the best clarity, and typical white LEDs consume substantially more current than the green ones used in first-generation mobile phones. A Semtech engineer offers this advisory.
Flexible 400mV reference a direct hit for portable medical equipment Product News 7/1/2004 Post a comment Linear Technology says its new LT6650 is the lowest voltage series reference available. The device features a built-in rail-to-rail output buffer amplifier and ±1% guaranteed accuracy from -40°C to 85°C. The LT6650 is ideally suited for portable industrial and medical equipment, plus low power instrumentation.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
