Abstract: A DC-DC converter includes an insulating substrate; a magnetic core embedded in the insulating substrate, the magnetic core having non-zero x, y and z dimensions of less than or equal to about 5.4 mm by about 5.4 mm by about 1.8 mm; separate primary and secondary transformer windings surrounding first and second regions of the magnetic core; and a control circuit including: an oscillator; a drive circuit coupled to the oscillator; and one or more switches coupled to the drive circuit; the drive circuit providing a switching signal to the one or more switches and energizing the one or more switches to provide a drive voltage to the primary transformer winding. The one or more switches are Field Effect Transistors implemented in a Silicon-on-Insulator configuration or as a Silicon-on-Sapphire configuration.
