Texas Instruments LM10520
The LM10520 is a single-phase 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 AVS technology enables optimum energy management delivery to the load in order to maximize system-level energy savings. The LM10520 operates cooperatively with PowerWise™ AVS-compatible ASICs, SoCs, and processors to optimize supply voltages adaptively over process and temperature variations.| Part No. | LM10520 |

DESCRIPTION
The device is controlled via the high-speed serial PWI 2.0 openstandard interface. It also supports Dynamic Voltage Scaling (DVS) using frequency-voltage pairs from pre-characterized lookup tables. The LM10520 features a fixed-frequency voltagemode PWM control architecture which is adjustable from 50 kHz to 1MHz with one external resistor.
