Abstract
The present invention relates to a Single Inductor Double Output (SIDO) power converter, which includes a power-stage circuit, a current detector, a slope compensation device, at least two error amplifiers, a comparing unit, a mode exchange circuit, a logical device and a driver. The SIDO current converter achieves an optimal SIDO power converting efficiency by controlling a full-current mode. Furthermore, different power transferring modes, under a variety of loadings, are used to address the issue of cross regulation and at meanwhile solving output voltage ripples and transient response to ensure the SIDO power converter a more flexible usage environment and better output performance.
