Abstract
Method determines a configuration of capacitors in an output filter of a switched mode power supply (SMPS). Candidate configurations are generated, each associated with a respective cost function value calculated based on number of capacitors of each kind in the candidate configuration and cost assigned to each kind of capacitor. The candidate configurations are ordered based on their cost function values. A binary search through the ordered candidate configurations determines a capacitor configuration associated with a lowest cost function value to allow a defined load transient response requirement of the SMPS. Whether a candidate configuration allows the defined load transient response requirement of the SMPS is determined using a model of a SMPS having the candidate configuration of the output filter simulating deviation of output voltage of the SMPS in response to change in load current of the SMPS and determining whether the defined load transient response requirement is allowed.
