Two different approaches to achieve robustness with respect to the input voltage, the reference voltage and the load variations in a step-down multiphase power converter are presented in this paper. The proposal allows both to regulate the output voltage to a given reference and to minimize the current ripple. Design is validated by means of simulation results.
