1. A small form factor power supply capable of providing between about zero and seventy five watts DC, the small form factor power supply comprising:

  • a low profile magnetic core for a transformer;

    a printed circuit board adapted to have various circuit components mounted thereon, wherein the printed circuit board defines certain wiring patterns including the wiring patterns for primary and secondary coils of the transformer that are magnetically coupled to the core;

    a driver circuit coupled to the wiring pattern for the primary coil;

    a rectifier circuit formed on the printed circuit board and coupled to the secondary coil to provide a DC power source capable of delivering between zero and seventy five watts of DC power; and

    a case enclosing the printed circuit board, the core and the circuit components such that a thickness of the case is less than about 0.436 inches, a length is less than about 5.0 inches, and a width is less than about 2.85 inches, wherein the case reaches a maximum temperature of less than about one hundred forty degrees Fahrenheit when the rectifier circuit delivers seventy five watts DC power.
