This application note discusses how to select optimal power devices and control circuitry for alternating plasma display panel applications, concentrating on power circuits used to sustain plasma discharge on the panel. Plasma Display Panels (PDP) are emerging as the leading candidate for large area wall- hanging color TVs and HDTVs [1.]. Its large screen, wide viewing angle, and thinness have given it the edge over conventional displays. Scan, Energy Recovery (ERC) and Sustain (discharge) circuits are important blocks that fulfill important energy saving requirements.
