The LM10500 is a 5A Energy Management Unit (EMU) that actively reduces system-level power consumption by utilizing a continuous, real-time, closed-loop Adaptive Voltage Scaling (AVS) scheme. The LM10500 operates cooperatively with PowerWise AVS compatible ASICs, SoCs, and processors to optimize supply voltages adaptively over process and temperature variations. The device is controlled via PowerWise Interface (PWI) 1.0 or PWI 2.0 high-speed serial interface.

A typical power saving of 40% can be achieved when LM10500 is used with AVS compatible ASICs, SoCs, and processors.
