Integrated Transformer

A system comprising:

• a first core comprising a first center leg, a first outer leg and a second outer leg over a first base;
• a first primary coil wound around the first center leg;
• a first multilayer PCB comprising a plurality of first inner windings, wherein the first multilayer PCB comprises a first connector and a second connector;
• a plurality of first electronic components disposed on the first multilayer PCB;
• a second multilayer PCB comprising a plurality of second inner windings, wherein the second multilayer PCB comprises a third connector and a fourth connector;
• a second primary coil wound around the second center leg;
• a plurality of second electronic components disposed on the second multilayer PCB;
• and
• a second core comprising a second center leg, a third outer leg and a fourth outer leg over a second base.

A method comprising:

• winding a first primary coil around a first center leg of a first core comprising a first outer leg, the first center leg and a second outer leg over a first base;
