Abstract
The present embodiments relate generally to DC-DC converters and more particularly to a scheme for providing current sharing between parallel converters in a multiphase configuration. In some embodiments, a cycle-by-cycle instant correction to the compensation signal offset is provided based on the current share error between the paralleled converters so as to achieve improved instant current share performance.
