Claim 9:
10. A buck voltage regulator device, comprising:
a first coupled inductor including a first primary winding and one or more auxiliary windings including a first auxiliary winding;
a first high-side switch electrically connected between an electrical energy source and a starting end of the first primary winding of the first coupled inductor;
a first low-side switch electrically connected between the starting end of the first primary winding of the first coupled inductor and a ground node;
a second low-side switch electrically connected between the electrical energy source and a starting end of the first auxiliary winding of the first coupled inductor, wherein the second low-side switch includes a drain, a gate, and a source, wherein the drain is coupled directly to the starting end of the first auxiliary winding of the first coupled inductor, and wherein the source is coupled directly to the ground node;
a second coupled inductor including a second primary winding and one or more auxiliary windings including a second auxiliary winding;
a second high-side switch electrically connected between the electrical energy source and a starting end of the second primary winding of the second coupled inductor;
a third low-side switch electrically connected between the starting end of the second primary winding of the second coupled inductor and the ground node;
a fourth low-side switch electrically connected between the electrical energy source and a starting end of the second auxiliary winding of the second coupled inductor, wherein the fourth low-side switch includes a drain, a gate, and a source, wherein the drain is coupled directly to the starting end of the second auxiliary winding of the second coupled inductor, and wherein the source is coupled directly to the ground node;
a first output node electrically connected to a terminal end of the first primary winding and the second primary winding;
a second output node electrically connected to a terminal end of the first auxiliary winding and the second auxiliary winding;
a first output storage capacitor electrically connected to the terminal end of the first primary winding and the terminal end of the second primary winding and electrically connected between the first output node and the ground node; and
a second output storage capacitor electrically connected to the terminal end of the first auxiliary winding and the terminal end of the second auxiliary winding and electrically connected between the second output node and the ground node.
