Patent ID: 8581562

Claim:
A Single Inductor Double Output (SIDO) power converter, comprising: a power-stage circuit, comprising an inductor, a first output terminal and a second output terminal; a first error amplifier, coupled to the first output terminal, for outputting a first error signal; a second error amplifier, coupled to the second output terminal, for outputting a second error signal; a current sensing circuit, for detecting a current of the inductor and outputting a first signal; and a comparing unit, coupled to the power-stage circuit and the current sensing circuit, for receiving the first error signal, the second error signal and the first signal, and adding the first error signal to the second error signal for generating a third error signal, and respectively comparing the first signal with the first error signal, the second error signal and the third error signal for generating a first comparison signal, a second comparison signal and a third comparison signal; wherein the power-stage circuit determines the energy transfer path according to the first, second and third comparison signals.
