Power Management is the systems engineering involved in
designing ICs and systems to efficiently and accurately
deliver electrical power to the various components in a
system. It involves efficiently converting unregulated
voltages derived from the AC line, batteries, or other
sources to regulated, precise and protected levels. Power
management ICs manage transitions between standby, sleep and
high power modes effectively. As systems become more
complex, PM ICs often include auxiliary functions such as
Audio, Li-Ion Charging, LED drivers to reduce overall cost
and size. Power Management devices help to extend battery
life in portable products. These solutions support products
that are popular in consumer (hand held/portable),
networking and computing, wireless, automotive and motor
control applications - especially for extremely specialized,
high performance products. |
