EN 32 9. LGE PDP 2K6 Circuit Descriptions, Abbreviation List, and IC Data Sheets 9.8 DC/DC Converter Part 9.9 FPC (Flexible Printed Circuit) 9.8.1 Purpose From 5V, Vs, and Va (from the PSU), the DC/DC converter makes 5V, 15V, Vy, Vsc, 5Vf, and Va, which are essential for each board. PSU YSUS Board 5V 5V 9.9.1 Purpose To supply a driving waveform to the PDP by connecting a PAD electrode of the PDP with a PWB (Y and Z boards). • There are two types of this for the Y board: One is single- sided, the other double-sided (these have a pattern on it). • For Z board there is no pattern, single-sided, and Beta type (all of copper surface). DC/DC Convert 15V 5Vf (Floating Voltage) Vs DC/DC Convert Vy Vsc G_16390_037.eps 100806 Figure 9-8 DC/DC Converter block diagram F_15590_058.eps 200605 Figure 9-10 Flexible Printed Circuit 9.10 FFC (Flat Flexible Cable) 9.10.1 Purpose For connecting LOGIC signals between boards. There are two types • 0.5 mm pitch, 50-pin type. • 1.0 mm pitch, 30-pin type.
