A power switch driver for driving a control terminal of a power switch to drive a load, the power switch driver having a negative feedback circuit to control current delivered to the control terminal. The negative feedback circuit has a current output circuit having a current source and a current sink and serving for providing the current of the control terminal and configured to receive an output current control signal to control a magnitude of the current provided by the current output circuit, a terminal voltage input circuit for receiving a voltage from the control terminal and to output an indication of the voltage, an amplifier coupled to the terminal voltage input circuit for amplifying the terminal voltage indication to generate an amplifier output, and a reference voltage input circuit for receiving a reference voltage, having at least one resistor, and coupled to a charge supply input of the amplifier.
