... Advanced Analog Technology, Inc. DESIGN PROCEDURE One of many important functions of AAT1301 is to minimize flicker in TFT-LCD panels by adjusting VCOM voltage. AAT1301 is attached to an external resistive voltage-driver to sink a programmable current (IOUT), which determines the VCOM voltage. Eq. 1 and Eq.2 can be used to calculate the output current (IOUT) and output voltage (VCOM) ...
