Abstract:
A current control system, and method for controlling current, and a lighting system including the same, are provided. The current control system includes front end circuitry to receive an input voltage and provide a regulated DC voltage to current source circuitry via a first input voltage terminal. Dimming interface circuitry provides a pulse width modulation signal to conversion circuitry, which uses the pulse width modulation signal to generate an analog voltage. The conversion circuitry sends the analog voltage to the current source circuitry via a second input voltage terminal. The current source circuitry uses the regulated DC voltage and the analog voltage to create an output current. The output current drives a load, which, in the lighting system, is one or more solid state light sources.
