US 10,320,215 B2 · Apparatus and method for instant on ability

Abstract

In an embodiment, a system includes voltage sensing logic to determine a first source voltage Vfirst source corresponding to a first source, and a controller to receive an indication of Vfirst source from the voltage sensing logic. The controller is to, responsive to Vfirst source>a first output voltage (V1), select a first source first regulator to input Vfirst source and provide V1; responsive to Vfirst source>a second output voltage (V2), select a first source second voltage regulator that inputs Vfirst source, and provide V2; responsive to Vfirst source≤V1, select a second source first voltage regulator that inputs a second source voltage Vsecond source that corresponds to a second source and is substantially constant in time where Vsecond source>V1, and provide V1 independent of the first source first regulator and the first source second voltage regulator. Other embodiments are described and claimed.
