8. A method, comprising:
providing a current from a charge pump, to a bootstrap capacitor, through a charge pump switch;
receiving a control signal that indicates a first mode of operation or a second mode of operation;
responsive to the control signal indicating the first mode, allowing a first value of current to the charge pump switch; and
responsive to the control signal indicating the second mode, limiting the current to the charge pump switch to a second value, wherein the second value is less than the first value.
