A device for driving a PDP for arranging scan electrodes and sustain electrodes in parallel for each display line, and arranging address electrodes to be crossed with the scan electrodes and the sustain electrodes. The device has a first switch and a second switch that are coupled in series between a first voltage and a second voltage, a capacitor coupled between a contact point of the first switch and the second switch and a third voltage. A rising ramp switch for forming a constant current is coupled to the third voltage at a first end of the rising ramp switch; and a main path switch is coupled between the contact point of the first and second switches and another end of the rising ramp switch, for forming a constant current.
