Abstract
There is presented a driver and a corresponding method for driving a p-type power switch. The driver includes a capacitor coupled to a control terminal of the power switch. The driver is configured to apply a control voltage to the control terminal and to connect the control terminal to ground to reduce the control voltage down to a target value to switch the power switch on. When identifying that the control voltage has reached the target value, the driver disconnects the control terminal from ground. The driver may be used in various circuits including switching power converters, audio amplifiers and charge-pump circuits.
