Abstract
A plasma display panel driver for applying a Zener diode to a falling ramp driving circuit, and reducing a falling ramp driving initial voltage to a voltage that causes a discharge. The driver comprises a transistor having a first electrode coupled between a first terminal of a panel capacitor and a power source; a capacitor having a first terminal coupled to a control electrode of the transistor; and a first resistor, a diode, and a Zener diode coupled in parallel between a second terminal of the capacitor and the first electrode of the transistor.
