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.
