Abstract

A monolithic DC to DC converter, provides a semiconductor substrate, a surface FET formed on the semiconductor substrate that modulates currents across a surface of the semiconductor substrate, and a toroidal inductor with a magnetic core formed on the substrate around the FET and having a first winding connected to the FET.
