Abstract
In an embodiment, an electronic device includes an integrated circuit (IC) having a plurality of power domains, a first regulator coupled to a given power domain, a second regulator coupled to the given power domain, and a switching circuit coupled between the first and second regulators and configured to control an amount of current drawn by the power domain from the first and/or second regulators. In another embodiment, a method includes controlling an impedance of a switching circuit to change an amount of current, the switching circuit coupled to a given power domain of an IC configured to operate in a first mode followed by a second mode, where the switching circuit is coupled to a first regulator configured to provide more power to the IC than a second regulator, and a transition period includes turning off the first regulator and turning on the second regulator.
