TPS65165 描述
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.
The device also features a high-voltage stress test, where the output voltage of VGH is typically set to 30 V, and the output voltage of Vs is programmable to any higher voltage. The high-voltage stress test is enabled by pulling the HVS pin high. Adjustable sequencing is implemented, and can be programmed by selecting the capacitor values connected to ADLY and GDLY
