An integrated circuit package comprises an integrated circuit die comprising a first pad, a second pad adjacent to the first pad, a third pad adjacent to the second pad, and a fourth pad adjacent to the third pad. Resonant inductor is placed in series with the hybrid transformer primary to insure the continuity of primary and secondary currents at the switching transitions and thus eliminating completely the potential switching losses at the switching transitions. The holder having a first aperture in the base, seating therein a generally rectangular magnet, which holds the ball marker until it is dislodged by a greater force.
