Claim Text:
1. A switching regulator comprising: a high-side MOSFET having a gate, a source, and a drain; a low-side MOSFET having a gate, a source, and a drain; a high-side driver circuit having an input and an output, the output of the high-side driver circuit being coupled to the gate of the high-side MOSFET to control the high-side MOSFET to be substantially depleted during a first operational phase and to be substantially enhanced during a second operational phase; a low-side driver circuit having an input and an output, the output of the low-side driver circuit being coupled to the gate of the low-side MOSFET to control the low-side MOSFET to be substantially enhanced during the first operational phase and to provide a regulated drain-to-source current during the second operational phase; and a capacitive coupling circuit, coupled to the input of the high-side driver circuit and the gate of the low-side MOSFET that decreases the regulated drain-to-source current during a transition from the first operational phase to the second operational phase.
