【Abstract】 This paper proves that a Single-inductor multiple-output (SIMO) DC-DC buck converter in Continuous-Conduc-tion Mode (CCM) can supply the output voltages higher than the input voltage, which will greatly reduce the design complexity ofSIMO DC-DC converters. A two-branch-output SIMO DC-DC experiment is carried out, with its input voltage 3.3V and output voltages 1V and 4V repectively. The experiemental results correspond well to the theoretically calculated ones, thus verifying ourderivations.更多还原
