Claim 16:
17. The method according to claim 13, wherein the construction of the built-in transformer comprises:
forming a first transformer primary coil on a first PCB layer and a second transformer primary coil on a sixth PCB layer;
electrically connecting the first transformer primary coil with the second transformer primary coil to form the transformer primary winding;
forming a first transformer secondary coil on a second PCB layer and a second transformer secondary coil on a fifth PCB layer;
electrically connecting the first transformer secondary coil with the second transformer secondary coil to form the transformer secondary winding;
disposing the first PCB layer adjacent to the second PCB layer such that the first transformer primary coil is magnetically coupled with the first transformer secondary coil to form a first transformer layer assembly; and
disposing the fifth PCB layer adjacent to the sixth PCB layer such that the second transformer primary coil is magnetically coupled with the second transformer secondary coil to form a second transformer layer assembly.
