This article presents a solution to the problems attached with switch-mode direct current (dc) to dc converters. New breakthroughs in semi-conductor processes and magnetic materials have enabled integration of the entire dc-dc converter, including ancillary components, into a single integrated circuit package. One result is enhanced control over the implementation, allowing converters to be made stable over a very wide range of input/output conditions with no layout-dependency issues. And integration of the magnetics makes it possible to dramatically reduce the noise associated with the large pulse currents that pass between the power switches and the inductor.
