Abstract
An electronic lamp dimmer includes a burst dimmer circuit and an analog dimmer circuit formed adjacent to each other on an integrated circuit substrate. The burst dimmer circuit controls the illumination intensity of a lamp over a first operating range and the analog dimmer circuit controls the illumination intensity of the lamp over a second operating range that overlaps the first operating range. The electronic dimmer includes a plurality of electrical contacts, each of which is electrically coupled to one of the burst dimmer and analog dimmer circuits and one of which simultaneously provides a dimming control voltage to both of the burst dimmer and analog dimmer circuits.
