A boost circuit effects increasing current flow through an inductor and a switch when the switch is closed, and then, when the switch is open, directs the inductor current through a diode to charge a storage capacitor at the output. A logic circuit operates the switch. The switch is controlled on by sensing low current flow in the capacitor and off by sensing high current flow in the switch, so that inductor current is continuous.
