Switching regulator with driver power clamp

A switching regulator with driver power clamp, comprising:

• an inductor and a first power switch, wherein a first terminal of the inductor is coupled to an input terminal of the switching regulator, and the first power switch is coupled between a second terminal of the inductor and a negative supply terminal of a power supply;
• a second power switch, coupled between the second terminal of the inductor and an output terminal of the switching regulator, wherein when the first power switch is turned off, a diode of the second power switch is forward biased to establish a current path from the second terminal of the inductor to a boost terminal of the switching regulator and then to the output terminal of the switching regulator;
• a first driver, configured to drive the first power switch;
• a second driver, configured to drive the second power switch;
• and
• a driver power clamp, configured to clamp a voltage of a ground terminal of the second driver;
• wherein:
• during transition intervals while the first driver switches the first power switch from an on-state to an off-state, the driver power clamp shifts the voltage of the ground terminal of the second driver to a higher level in comparison with a normal internal ground level of an internal ground of the switching regulator;
• and
• prior to switching the first power switch from the on-state to the off-state, the ground terminal of the second driver is at the normal internal ground level.
