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.
