LM10500 Datasheet | Texas Instruments

FEATURES - 23 Closed-Loop Adaptive Voltage Scaling (AVS) - PWI 1.0 / PWI 2.0 patible - 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 Power Wise™ AVS patible ASICs, So Cs, and processors to optimize supply voltages adaptively over process and temperature variations. The device is controlled via Power Wise 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 patible ASICs, So Cs, and processors.
