Claim 1:
2. The power supply apparatus with step-up and step-down conversion as claimed in claim 1, wherein the voltage regulator is a step-down converter, wherein the step-down is configured to operate in any of the following different operation modes based on the voltage regulation signal,
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
when the voltage regulation signal controls the step-down converter to operate in an idle mode, and the step-down converter does nothing for the DC output voltage.
