Power management system and method to provide supply voltage to a load

A power manager controls the supply voltage level at a load according to load current demand, and optionally the impedance of the power delivery path, by adjusting the supply voltage. The supply voltage may be reduced by determining a fixed load current that corresponds to a first operating frequenc...

Beschreibung
Zusammenfassung:	A power manager controls the supply voltage level at a load according to load current demand, and optionally the impedance of the power delivery path, by adjusting the supply voltage. The supply voltage may be reduced by determining a fixed load current that corresponds to a first operating frequency, determining a supply voltage that corresponds to the fixed load current, and then powering the load based on the supply voltage. Alternatively, the supply voltage may be increased along with increasing the operating frequency of the load while maintaining system power consumption within a predetermined limit.
