Classification: CPC H  Y | IPC H

Claim 3:
4. The power supply apparatus with step-up and step-down conversion as claimed in claim 1, wherein the voltage regulator comprises a step-down converter and a bypass circuit,
when the voltage regulation signal controls the step-down converter to operate in a step-down mode, the step-down converter steps down the DC output voltage to the output voltage, or
when the voltage regulation signal controls the step-down converter to operate in a pass-through mode, the step-down converter passes through the DC output voltage as the output voltage or controls the bypass circuit to bypass the DC output voltage as the output voltage, or
when the voltage regulation signal controls the step-down converter and the bypass circuit to operate in an idle mode, the step-down converter and the bypass circuit do nothing for the DC output voltage.
