The TPS65190 is a combined multi-channel level-shifter and VCOM 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 VCOM 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 VGH1 and channels 7-8 are supplied by VGH2. 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 VGL.
The level-shifters feature low impedance output stages that achieve fast rise and fall times even when driving significant capacitive loads.
The uncommitted high-speed operational amplifier features a high slew rate and high peak current capability that make it particularly suitable for driving the panel's common rail (VCOM).
