The power appetite of large TFT-LCDs appears to beinsatiable. Power supplies must feed increasing numbersof transistors and improved display resolutions, and doso without taking much space.
The triple output supply shown in Figure 1 shows a compactdesign based on the LT3489, which is optimized fordriving large TFT panel displays. The main output provides8V at 600mA while the 23V and –8V outputs provide 10mAand 20mA respectively, all from a 3.3V input. Even thoughTFT converters generally run from a regulated 3.3V or5V source, this converter can operate seamlessly froma Lithium-Ion battery, delivering 5W when the battery isdrained to 3.3V and 8W when it is at 4.2V.
