The fast response double buck DC-DC converter (FRDB)

A new low output voltage and fast transient response DC-DC converter is presented in order to feed devices such as microprocessors and DSPs. The topology of the fast response double buck DC-DC converter (FRDB) is composed of two buck converters connected in parallel, each one of them with different features and aims, and controlled by means of the novel linear-nonlinear control. In this paper, the proposed topology and the control strategy are described. Finally, experimental results are presented to show the transient response under load current steps and the obtained recovery time.
