3.5A, 6V step-down converter needs only 40-μA quiescent current

...Targeting handheld and portable devices requiring only one single-cell lithium-ion battery, the MP2130 synchronous step-down converter from Monolithic Power Systems features a quiescent current of only 40 μA. The 3.5A, 6V, 1.2-MHz device fits into a 2×2-mm QFN package. It achieves a 96% efficiency at a load current of 1A and an output voltage of 3.3V, and it still maintains an efficiency of 85% at a load current of 0.01A. You can regulate the output voltage as low as 0.6V. The constant-on-time-control approach provides fast transient response, high light-load efficiency, and fast loop stabilization...

GM: We're not pulling plug on Chevy Volt

... storage analyst for Lux Research."The technology is very solid," Cole said. "But the economics are just not there right now. The batteries, power electronics, and motor-generator technologies are still too expensive." In terms of economics, batteries are the biggest problem. Cole estimated that battery packs continue to cost automakers $800/kWh to $1,000/kWh. Sathawane put the figure "...
