Abstract
Methods and systems are disclosed for an integrated voltage regulator with open loop digital control for power stepping. In one aspect, a method for regulating an output voltage includes receiving data indicative of a power setting associated with an identified state of an electrical circuit, the power setting based on a load current demand of the electrical circuit in the identified state, enabling one or more parallel driver segments based on the received data indicative of the power setting. The method further includes sourcing by the enabled one or more parallel driver segments sufficient current to meet the load current demand of the electrical circuit in the identified state while maintaining the output voltage at a predetermined voltage level, and providing the output voltage to the electrical circuit at the predetermined voltage level.
