Abstract
An LED driver includes a main power source, a transistor connected to a controller, an inductor, a diode, and a capacitor. The inductor is connected to a diode at a first end and connected to a main power source and the capacitor at a second end. The diode is also connected to the capacitor. The controller is configured to switch the transistor between an active state and an inactive state. When the transistor is in the active state, the inductor is charged by the main power source. When the transistor is in the inactive state, the inductor charges the capacitor through the diode until a capacitor current is greater than a diode current. At which point, the capacitor's voltage is in series with the main power source's voltage, and the sum of their voltages supply power to LED(s) connected to the capacitor.
