Abstract
A semiconductor circuit for driving a load, comprising a transformerless Alternative Current (AC) to Direct Current (DC) converter integrated circuit that includes a high voltage circuit fabricated on a substrate for converting a high voltage AC input signal to a first high voltage DC output signal. Further included is a second circuit fabricated on the same substrate for regulating a drive signal for driving a load using power from the first high voltage output signal, with the high voltage circuit and the second circuit fabricated on the substrate to form a single integrated circuit (IC) chip.
