Power Management Design for Portable and Battery Powered Systems

摘要

Integrating the maximum number of functions plus power rnanagement into the main chipset for portable, battery powered devices such as mobile phones with capability such as MP3, Mpeg4, and TV,rnwould seem to be critical if an acceptable length of battery life is to be achieved.rnSet against this is a contradictory desire from OEMs not to adopt a fully integrated approach. This is due to the potential poor flexibility and long development cycle times of integrated ICs and chipsets when compared to the rapid rate at which new handset designs evolve.
