Optimizing Power Systems For Portable Electronic Devices

摘要

System architects can optimize power-system efficiency by selecting the best system voltages for the application, using the right power-supply elements, and designing all the power-system elements to work together to reduce battery drain.rnPortable electronic devices are a huge part of our everydayrnlives, with most consumers owning at least one mobile phone and usually at least one other device. Throw in the ubiquitous notebook computer, which-according to iSuppli-will represent 40% of total PC unit shipments by 2010, and this becomes a vast number of portable products. As a result, several types of portable devices, including notebooks, mobile phones, MP3 players and personal digital assistants (PDAs), have become significant drivers of the power management market.
