LM10500 Overview
The LM10500 is a 5 A 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
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.

Adaptive Voltage Scaling Technology
PowerWise Adaptive Voltage Scaling (AVS) technology is an advanced closed-loop technology for
reducing active and standby energy consumption of digital processing engines and ASICs. Hardware
Performance Monitor (HPM) is designed into the digital engine together with an Advanced Power
Controller (APC) to monitor the performance of the silicon based on process and temperature variation.
Information is fed back to an Energy Management Unit (EMU) which then sets the voltage precisely
according to the processor’s needs. The AVS technology enables optimum power delivery to the
processors, ASICs, and SoCs, which maximizes overall system energy savings. AVS technology is
process and architecture independent.
