Patent ID: 7804698

Claim:
A voltage regulator comprising: an input configured to receive a voltage from a battery; a capacitor having first and second terminals and configured to be selectively coupled between the input and a charging node to charge the capacitor and between the input and an output of the voltage regulator to supply current to the output; a first transistor operably coupled to selectively couple the first terminal of the capacitor to supply the current to the output of the voltage regulator; a second transistor operably coupled to selectively couple the second terminal of the capacitor to the input to supply the current to the output wherein the first transistor and the second transistor are enabled substantially simultaneously; and a first driver having an output stage configured to drive a control electrode of at least one of the first transistor or the second transistor with a drive signal having an edge that has a first time dependent transition time having a first time constant that is between about five and seventy-five percent of a frequency of a signal received by the driver and using the edge to enable one of the first transistor or the second transistor to operate in a linear operating mode during the transition time prior to fully enabling the switch after the transition time.
