www.DataSheet.co.kr 19-4809; Rev 0; 8/09 TION KIT EVALUA BLE A IL A AV Triple High-Voltage Scan Driver for TFT LCD General Description The MAX17120 includes three high-voltage level-shifting scan drivers for TFT panel integrated gate logic. Each scan driver has two channels that switch complementarily. The scan-driver outputs swing from +40V to -30V and can swiftly drive capacitive loads. To save power, the scan-driver’s complementary outputs share the charge of their capacitive load before they change states. The MAX17120 is available in a 32-pin, 5mm x 5mm thin QFN package with a maximum thickness of 0.8mm for ultra-thin LCD panels.
