A driver control circuit and method for a cold cathode fluorescent lamp (CCFL), that the driver control circuit comprises: at least a comparator; at least an input/output port, at least an analog-to-digital converter; at least two programmable pulse generators (PPGs), including a first programmable pulse generator and a second programmable pulse generator, i.e. PPG 0 and PPG 1 , being activated for generating pulse signals in an alternative manner for driving the CCFL; at least a programmable frequency divider (PFD), capable of programming the output thereof to be used as the control signal for activating the PPG 0 and the PPG 1 according to the alternative manner defined by the transition frequency of the PFD.
