ABSTRACT:
A fluorescent lamp ballast control circuit includes a ballast controller IC for driving a fluorescent lamp in a half-bridged topology and a control circuit. The control circuit receives an input signal and provides an output signal to the ballast controller IC. The control circuit further receives a feedback signal indicative of the fluorescent lamp current. The control circuit output signal is based on the input signal and the feedback signal. The fluorescent lamp ballast control circuit is used in combination with a fluorescent lamp ballast.
