Phase reconfigurable switching power supply

摘要

Embodiments of circuitry, which includes power supply switching circuitry and a first inductive element, are disclosed. The power supply switching circuitry has a first switching output and a second switching output. The first inductive element is coupled between the first switching output and a power supply output. The power supply switching circuitry operates in one of a first operating mode and a second operating mode. During the first operating mode, the first switching output is voltage compatible with the second switching output. During the second operating mode, the first switching output is allowed to be voltage incompatible with the second switching output.

1. Circuitry comprising:
a power supply output; and power supply switching circuitry having a first switching output and a second switching output, wherein:
a first inductive element is coupled between the first switching output and the power supply output;the power supply switching circuitry is adapted to operate in one of a first operating mode and a second operating mode;during the first operating mode, the first switching output is voltage compatible with the second switching output such that the first switching output is directly coupleable with the second switching output; andduring the second operating mode, the first switching output is allowed to be voltage incompatible with the second switching output such that the first switching output is not directly coupleable with the second switching output.
