Using SPICE for multiple-constraint choice of capacitor bank for telecom power supplies

This paper proposes the selection of the output capacitor bank for the synchronous dc/dc buck converters based on PSPICE modeling and simulation of various combinations of ceramic and electrolytic capacitors. Multi-constraint choice is made with output voltage ripple, voltage deviations at step change of load current, and duration of the transitions due to step load change.
