Abstract

A new alternative to get fast transient response DC/DC switching converters is presented in order to feed devices such as microprocessors and DSPs. The topology of the switching power supply is composed of two buck converters connected in parallel, each one of them with different aims, controlled by means of the linear-nonlinear control. In this paper, the LNL control is reviewed and applied to the proposed power supply (fast response double buck, FRDB). Also, experimental results are obtained to show the main features of the proposed converter and to compare them with the features of some other solution.
