A transformer device includes first, second, and third windings, located in an insulating substrate by conductive vias joined together by conductive traces. Positions of the conductive vias are arranged so as to optimize the isolation properties of the transformer, and to improve the coupling of the transformer by increasing the leakage inductance and reducing the distributed capacitance. The transformer device is compact and is weakly coupled. The weak coupling between the windings reduces the likelihood of the transformer malfunctioning, particularly when used in a self-resonant converter circuit.
