LM10520 - Texas Instruments

LM10520 Single-Phase Buck Controller

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 .
