LM10500 www.ti.com SNVS630G – SEPTEMBER 2009 – REVISED MARCH 2013 LM10500 5A Step-Down Energy Management Unit (EMU) With PowerWise™ Adaptive Voltage Scaling (AVS) Check for Samples: LM10500 FEATURES 1 23 Closed-Loop Adaptive Voltage Scaling (AVS) PWI 1.0 / PWI 2.0 Compatible Resistor-Programmable switching frequency Frequency Synchronization Precision Enable Internal Soft-Start to Reduce In-Rush Current Power Good (PWROK) Under-Voltage Lock Out (UVLO) Over-Voltage Protection (OVP) Cycle-by-cycle current limiting (OCP) Thermal Shutdown 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.
