摘要： A circuit for controlling a switching regulator is provided. The circuit includes a first input to receive a feedback signal from the switching regulator proportional to an output voltage of the switching regulator, a second input to receive a voltage reference signal, an output to be coupled to an input of the switching regulator, an error amplifier having a first input terminal coupled to the first input to receive the feedback signal, a second input terminal coupled to the second input to receive the voltage reference signal, and an output terminal coupled to the output, and a compensation network coupled between the second input and the output. The compensation network includes a series combination of a first capacitance and a first resistance coupled between the second input and a node, a second resistance coupled between the node and the output, and a second capacitance coupled to the node.

摘要： A switching regulator that includes a high-side MOSFET, a low-side MOSFET, a high-side driver circuit, a low-side driver circuit, and a capacitive coupling circuit. An output of the high-side driver circuit is coupled to a 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. An output of the low-side driver circuit is coupled to a 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. The capacitive coupling circuit is coupled to an input of the high-side driver circuit and the gate of the low-side MOSFET and decreases the regulated drain-to-source current during a transition from the first operational phase to the second operational phase.
