DESCRIPTION
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.
