摘要：
Circuits and methods to correct the load sharing in multiphase switching regulators are provided. Using these systems and methods, the input capacitor voltage signal can be sampled and used for current sensing of the regulator's stages. Differences in the amount of output current for a converter stage can then be determined. Corrections needed to equalize the output current of the converter stages can then be determined and carried out.
