AAT1137 Overview
The AAT1137 is a highly integrated power management IC for TFT LCD panels. The device consists of two current mode boost regulators, a current mode buck regulator, a negative charge pump regulator, a reset function, and two operational amplifiers. The AAT1137 also includes I2C interface for setting various parameters such as each regulator’s output voltage, switching frequency, soft start time, delay times, buffer...
