ABSTRACT:
A power supply switching regulator including a common terminal; an input terminal for supplying a direct current input; an output terminal; a recirculating diode having a first terminal connected to the common terminal; an inductor having a first terminal connected to a second terminal of the recirculation diode and a second terminal connected to the output terminal; a capacitor having a first terminal connected to the output terminal and a second terminal connected to the common terminal; a switch connected between the input terminal and the first terminal of the inductor, the switch operable for switching between an ON state in which the direct current input is coupled to the inductor, and an OFF state in which the direct current input is isolated from the inductor; and a controller coupled to the switch and operable for controlling the amount of time the switch is in the ON state and the OFF state such that the duration of time the switch is in the ON state is inversely proportional to the difference between the voltage at the input terminal and the voltage at the output terminal.
