| 20100102784 | Soft-Switching Voltage Regulation in a Step-Down Circuit - An information handling system may comprise a direct-current to direct-current step-down power converter, a memory, and a processor. The step-down power converter may include a first inductive unit, a first switching unit connected between a voltage source and the first inductive unit, a second switching unit connected to ground, a capacitance unit connected between the second switching unit and the first inductive unit, and a second inductive unit connected between the second switching unit and the first inductive unit. The capacitance unit is configured to delay a change in voltage across the first or second switching units, and the second inductive unit is configured to delay a change in current in the first or second switching units. | 04-29-2010 |
