Abstract: An apparatus for driving a voltage source such as a discharge or LED lamp using a power booster receiving an AC voltage source configured through an inductor to turn on and off periodically in response to a duty cycle of a dimming control signal or a transformer starting a new cycle, for regulating a low voltage AC signal. The booster control circuitry adjusting the current feed to a determined target boost voltage according to sensed input from primarily a single comparator which compares any one of (but not limited to) a) the output boosted voltage, b) the globe current, or c) the inductor input current.
