TPS65191 用于 LCD 显示屏的 7 通道电平转换器（三通道扫描驱动器）
TPS65191 描述
The TPS65191 is a triple high-voltage scan driver to drive an ASG (amorphous silicon gate) circuit on TFT glass.
Each single high-voltage scan driver receives logic-level inputs of CPVx and generates two high-voltage outputs
of CKVx, CKVBx. The device receives a logic-level input of STV and generates a high-voltage output of STVP.
These outputs are swings from Voff (–28 V) to Von (35 V) and are used to drive the ASG circuit and
charge/discharge the capacitive loads of the TFT LCD. In order to reduce the power dissipation of device, a
charge-share function is implemented. The device features discharge function, which shorts Voff to GND in order
to shut down the panel faster when the LCD is turned off.
