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.
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
