Abstract
Methods and apparatus relating to low power optimized voltage regulators are described. In one embodiment, a voltage regulator controller may cause leakage current from a load to drain a capacitor (e.g., coupled in parallel with the load) during a reduced power state.
Claims14
An apparatus comprising:
- a voltage regulator controller to control a level of a voltage supply coupled to drive a load;
- a capacitor coupled to the load in parallel, to maintain the voltage supply level in accordance with a specified tolerance limit,
- wherein the voltage regulator controller causes leakage current from the load to drain the capacitor during a reduced power state.
A method comprising:
- controlling a level of a voltage supply coupled to drive a load in response to a first signal;
- sensing the voltage supply level;
- and
- causing leakage current from the load to drain a capacitor, coupled to the load in parallel, during a reduced power state.
