1 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 through 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.
2 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 needs of the processor. 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.
