    Abstract: A switching regulator clamping the power or ground of the power switch driver is introduced. In a buck regulator, the first power switch is coupled between the input terminal of the buck regulator and the first terminal of an inductor. The second terminal of the inductor is coupled to the output terminal of the buck regulator. The second power switch is coupled between the first terminal of the inductor and an internal ground of the buck regulator. There is a driver power clamp configured to clamp the power terminal of the driver of the second power switch when the first power switch is turned off. In a boost regulator, a driver power clamp is configured to clamp the ground terminal of the driver of the power switch that couples the input inductor to an output terminal of the boost regulator when another power switch is turned off.

    Abstract: A switching regulator clamping the power or ground of the power switch driver is introduced. In a buck regulator, the power switch is coupled between the input terminal of the buck regulator and the first terminal of an inductor. The second terminal of the inductor is coupled to the output terminal of the buck regulator. There is a driver power clamp configured to clamp the ground terminal of the driver of the power switch. In a boost regulator, an inductor is provided which has a first terminal coupled to an input terminal of the boost regulator and has a second terminal coupled to the negative supply terminal of the power supply through a power switch. The boost regulator has a driver power clamp that is configured to clamp the power terminal of the driver of the power switch.

    Abstract: A DC-DC converter includes an inductor, a switch module, a pull-up circuit and a pull-down circuit. The inductor has a first node and a second node, and the second node is coupled to an output node of the DC-DC converter. The switch module is arranged for selectively connecting an input voltage or a ground voltage to the first node of the inductor according to a driving signal. The pull-up circuit is arranged for selectively providing a first current to the output node of the DC-DC converter. The pull-down circuit is arranged for selectively sinking a second current from the output node of the DC-DC converter. In addition, at least one of the first current provided by the pull-up circuit and the second current sunk by the pull-down circuit is determined based on an inductor current flowing through the inductor.
