September 11, 2008 Applications Drive Component Power Designs
Power designers often prefer particular power products or manufacturers. Some designers try to drive these preferences into every application. That’s not surprising. Such choices are usually based on successful relationships with specific manufacturers. The designers already know the products, or they can rely on a level of reliability, on-time delivery, or good prices. Many suppliers of dc-dc converters offer common input and output voltages, power levels, and features....

July 10, 2008 Protect Yourself From The Dangers Of Knockoff Battery Packs
In recent years, the news of individual battery incidents such as cell-phone and laptop fires has been eclipsed by factory fires and large recalls of lithium-ion (Liion) cells. Several large, well-known Li-ion cell suppliers have been affected. The most notable event was the recall of Sony batteries in 2005. Panasonic and, more recently, LG Chemical have had fires affecting their Li-ion manufacturing volume as well. While these factors present challenges for...

June 12, 2008 The Polymorphous Landscape Of Bus Voltages
Voltages are bussed around all the time, but the applications and voltage levels are many and diverse. One of the high-voltage apps du jour, for example, is the data center. Everybody knows about the phenomenal rise of the Internet over the last few years, but few think much about how all of the generated data gets stored and distributed. To enable this capability, the emergence and growth of datacenters or server farms—and the power they increasingly...

April 10, 2008 You've Got High-Power Battery Questions, We've Got Answers
Historically, the nickel-cadmium (NiCd) cell has been the best solution for handheld applications with usage profiles requiring large current pulses. But new environmental regulations may have a marked effect on cells containing heavy metals such as cadmium. Meanwhile, a new variety of lithiumion (Li-ion) cells can support the high discharge currents required for many applications. Such batteries with high discharge rates represent a shift in Li-ion...

March 13, 2008 Demanding Dynamic Loads: Can Power Devices Keep Up?
With each new generation of processor, the trend is toward lower voltages, higher currents, and faster dynamic loads. As a result, power-system designers are challenged to provide ever-faster transient response. They also have to do it using less board area while providing cost-effective and efficient power-systems solutions that offer the requisite performance. The question is if power devices can keep up. Power designers traditionally responded to the need...
