Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2009. Includes bibliographical references (leaves 65-66). To address the need for multiple regulated voltage supplies in electronic devices, this thesis presents a modeling and design study of a single-inductor, multiple-output (SIMO) DC-DC buck converter with parallel source transient recovery. This converter would provide substantial cost and space savings over traditional options for producing multiple supply voltages. Operating in pseudo-continuous conduction mode (PCCM), it can supply heavy loads while not suffering from cross-regulation problems. The parallel current source circuitry at each output will greatly dampen any voltage spikes that may occur due to sudden load changes, thus improving transient performance. While the entire converter could not be nicely simulated as envisioned, the initial steps and accomplishments outlined in this thesis show definite promise. The proposed converter certainly merits further research, as the problems encountered here most likely stem from implementation and control issues rather than fundamental flaws in the idea. by Charles Jackson King III.
