Power density conundrumsRichard WilsonOne of the myths of electronics has been that power supply design was always the lastbit of a project to be tackled, implying that it was thrown together in haste. This mayhave once had the ring of truth about it, but not any more. High processor speeds, evermore restrictive space constraints, not to mention the trend for ...

Liion roars …at a priceSteve BushLithium ion batteries are in all the best phones and camcorders, so why are they noteverywhere, in every bit of portable test equipment for instance? A simple answer is cost.Liion batteries are more expensive to buy than NiCd or NiMH cells. “Lithium batteries are lighter than nickel cadmium or nickel metal hydride,”says Robin Cloke, MD ...

Low down on DC-DCsRichard WilsonProcessor and logic manufacturers continue to place power supply design under a lot ofpressure, especially where low voltage devices are concerned. With supply voltages forleading devices such as microprocessors dropping sub-1.0V, maintaining efficiency of powersupplies is tremendously difficult. As supply voltages approach 0.6V they are getting dangerously close to the voltage dropacross the diodes typically used ...
