Hi Team,

If I don't use the function of VCOM, could I just leave AVDD/POS/NEG/OUT/GND floating or any suggestion?

Hello,

If this VCOM buffer function is not used, please connect all of its pins (AVDD/POS/NEG/OUT/GND ) to GND.

Kind Regards,

Liaqat

Hi Liaqat,

Thank you for your feedback. Could you let me know if there is any risk and effect when we don't use Vcom amplifier?

Hi Roy,

As far as TPS65190 is concerned, there is no risk if VCOM buffer is not used.
