Use supercapacitors to drive a white LED camera flash Design How-To 5/13/2005 Post a comment LED photoflash solutions using supercapacitors, with combined high capacitance (1F or more), and low ESR (< 100milli-ohms), provide the pulse power required by the LED without taxing the battery. A Cap-XX applications engineer offers two complete designs for camera phones. One solution places supercapacitor at the output of a buck-boost converter; another solution uses a supercapacitor in series with the battery. From the May issue of Planet Analog magazine, here's the complete design analysis.

ADI's data converter business reflects a mixture of standbys and custom brews Product News 5/2/2005 Post a comment Today's data converter applications reflect an entirely new mixture of specifications and part types, Analog Devices' VP Dick Meaney (right) told EE Times last week. It's not so much that balance between standard linear building blocks and ASSPs has changed, ADI said. Rather, the applications for ASSPs have themselves shifted, and are now demanding entirely different specifications, technologies and engineering tradeoffs. Steve Ohr filed this report.
10-bit serial latched LED driver aimed at automotive systems Product News 5/2/2005 Post a comment A family of solid-state illumination products has been expanded with a new white LED driver targeted at LED indicator and interior lighting applications. The CAT310 from Catalyst Semiconductor Inc. drives up to 10 color, or white, LEDs and safely handles load dump transients to 40-V, making it suitable for automotive systems.
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.
