Power Management Archive
January 2008 - July 2008
Technology Insights on Power Management offer techniques for
conserving battery life in cell phones and portables, power
conservation trends for desktops, and power distribution topologies
for servers and card cages. Some of the industry’s best experts have
published articles on the use of switch-mode power supply controllers,
low-dropout linear regulators (LDOs) and offer choice words on the power
efficiency of handsets, PDAs and Pentium-based computers.
