Texas Instruments LM10520MH/NOPB

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. The device is controlled via the high-speed serial PWI 2.0 open-standard interface. It also supports Dynamic Voltage Scaling (DVS) using frequency-voltage pairs from pre-characterized lookup tables.

The LM10520 features a fixed-frequency voltage-mode PWM control architecture which is adjustable from 50 kHz to 1MHz with one external resistor. In addition, the LM10520 allows the switching frequency to be synchronized to an external clock signal over the range of 250 kHz to 1MHz. This wide range of switching frequency gives the power supply designer the flexibility to make better tradeoffs between component size, cost and efficiency.

Features include the ability to startup with a pre-biased load on the output, soft-start, input under-voltage lockout (UVLO) and Power good (based on both under-voltage and over-voltage detection). In addition, the soft-start pin can be used for implementing precise tracking, for the purpose of sequencing with respect to an external rail.
