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