摘要： An illumination brightness control apparatus receives an input voltage from a light dimmer and produces a control signal to regulate a drive signal to a power conversion switch of a switching mode power converter. The apparatus includes a voltage conditioning circuit to condition the dimmer input voltage to provide a conditioned voltage signal; an ADC circuit to sample analog data of the conditioned voltage signal at a sampling rate that is high relative to a nominal variation rate of the dimmer input voltage and to provide digital data corresponding to the sampled analog data; a digital signal processing circuit to produce a running data average of the digital data; and a controller to produce a signal corresponding to the running data average as the control signal to regulate the drive signal.
