Abstract
Methods and systems for operating a voltage regulator are described. A integrated circuit can be configured to adjust at least one of a deadtime parameter and a drive strength parameter of a power stage based on at least one of an input voltage being provided to a power stage, a switch node voltage of the power stage, and an output current of the power stage. A controller of the power stage can be further configured to adjust a deadtime of the power stage based on adjustment of the deadtime parameter. The controller can be further configured to adjust a drive strength of the first driver and the second driver based on adjustment of the drive strength parameter.
