Abstract: A system and apparatus including a light emitting diode (LED) driver provides an operating DC voltage to a plurality of LEDs connected in series (LED array) for providing illumination. A rectifier circuit and a filter are coupled to an AC power supply and provide a rectified and filtered DC source voltage to a transformerless voltage boost circuit, which provides the operating DC voltage to the LED array. A hysteretic self-oscillating circuit drives the transformerless voltage boost circuit at an oscillation frequency. A tap is connected between two LEDs in the LED array, which provides an auxiliary DC voltage, which is used to power the oscillating circuit and which eliminates the need for the LED driver to have a conventional transformer or auxiliary DC-DC power converter. The transformerless voltage boost circuit includes an inductor, a capacitor, a diode, and a switch wherein the switch is controlled by the oscillating circuit.
