摘要： A backlight inverter for an LCD panel of an asynchronous pulse width modulation (PWM) driving type which is capable of driving a plurality of cold cathode fluorescent lamps (CCFLs) in pairs and controlling a plurality of PWM drive signals for respective operations of the lamps to make the phases thereof different. The backlight inverter comprises a main driving integrated circuit (IC), at least one sub-driving IC, and a plurality of lamp operating circuits for operating the pairs of lamps in response to the first and second PWM drive signals and the third and fourth PWM drive signals, respectively. The lamps have different PWM on/off periods so that overshoot of a power supply circuit can be reduced so as to keep the entire system power stable.

摘要： An LCD backlight inverter includes a soft starter for generating a soft-start reference voltage gradually increasing as the driving power begins to be supplied. The LCD backlight inverter also includes a first error detector for receiving a first feedback voltage indicating the magnitude of driving current of the lamp and for comparing a smaller value out of a predetermined first reference voltage and the soft-start reference voltage with the first feedback voltage to generate a first error signal corresponding to the difference between the smaller value and the soft-start reference voltage. The LCD backlight inverter further includes a pulse width modulation comparator for comparing the first error signal and a triangle wave oscillation signal to output the pulse width modulation control signal with a predetermined duty ratio. The LCD backlight inverter prevents application of over-current and over-voltage to the LCD backlight to prolong the lifetime of the backlight.
