Hello:
I have been working on a design to drive a TFT display from a TI DSP processor. I looking to use TI TPS65150 to provide most of the voltage rails needed by the TFT panel. The schematic pages for the circuits are attached.
In reviewing the display documentation, it looks like my current implementation to generate the VCOM voltage is not sufficient, and I need to use a VCOM buffer amp instead. Some of the TI LCD power management ICs (such as the TPS65146) have this functionality built in. I could switch to one of these parts, but I want to find out if I could just add the buffer amp.
Can you make a recommendation for this?
Any feedback or input is welcomed and appreciated!
Thanks again!
Paul
