AAT1218 Overview
The AAT1218 is a highly integrated power management IC for TFT LCD TV panels. The device consists of a current mode boost regulator, three current mode buck regulators, a positive charge pump regulator with temperature pensation, a negative charge pump regulator, and gate pulse modulation. All of output voltages are set via I2C interface.
