Regulator IC extends adaptive power management

Santa Clara, Calif. – National Semiconductor’s LP5550 is the first digitally-controlled energy management unit (EMU) for handheld consumer products that implements the company’s PowerWise architecture for adaptive voltage scaling, thus cutting power consumption in stand alone digital processors. In conjunction with the company’s advanced power controller (APC, technology licensed from ARM, Ltd.) and the PowerWise Interface (PWI) open-industry standard, the LP5550 reduces power consumption in digital processor cores by up to 70 percent.
