DESCRIPTION
The TPS65165 is a Compact LCD Bias IC with 3 high-speed operational amplifiers for gamma correction and/or
VCOM supply. The device generates all 3 voltage rails for TFT-LCD displays (Vs, VGL and VGH). The device
incorporates a high-voltage switch that can be controlled by a logic signal from the timing controller (TCON) to
provide the gate-voltage modulation for VGH. If this function is not required, the CTRL pin can be tied high.
