The TPS65190 is a combined multi-channel level-shifter and V_COM buffer intended for use in large format LCD display applications such as TVs and monitors. The device converts the logic-level signals generated by the Timing Controller (T-CON) to the high-level gate drive signals used by the display panel and amplifies/buffers an externally generated V_COM voltage.

The 10 level shifter channels are organized as 2 groups, each with its own positive supply. Channels 1-6 and 9-10 are supplied by V_GH1 and channels 7-8 are supplied by V_GH2. The two positive supplies can be tied together if one positive supply voltage is used for all level shifter channels. Both level shifter groups use the same negative supply V_GL.

The level-shifters feature low impedance output stages that achieve fast rise and fall times even when driving significant capacitive loads.
