Abstract
An apparatus and method for driving a plasma display panel and includes two ramp switches. The two ramp switches are used to apply a two-step falling ramp waveform to a Y electrode of the plasma display panel in a reset period, thereby lowering a withstand voltage of a switch which is formed on a main path to block the flow of current when the falling ramp waveform is applied.
