An inverter driver device and a lamp driver device thereof are provided to control driving voltage to make a feedback voltage be stronger than the set voltage by using feedback voltages corresponding to a driving voltage and a driving current. An inverter(200) converts an input voltage into a driving voltage of plural discharge lamps(CCFL1-CCFL4). An inverter driving apparatus(100) controls the driving of an inverter by using the maximal values in the first and second feedback voltages corresponding to the driving voltage and the driving current in the plural discharge lamps.
