Abstract: Methods and apparatus for providing a time-interleaved current-feedback droop function for multiphase buck converters. An example method includes outputting a first control signal to enable a first set of switches corresponding to a first voltage of a first phase from a multiphase converter, the first phase included in a plurality of phases; enabling a first current associated with the first phase to be measured by a sample and hold circuit associated with the first phase; sampling the first current; holding the first current, the first current based on a load current for the first phase of the multiphase converter; and outputting a droop voltage based on a plurality of currents corresponding to the plurality of phases of the multiphase converter, the plurality of currents including the load current for the first phase.
