Hello,
I am using the TPS65070, but do not require the touchscreen. What should I do with the four inputs (AD_IN1-4)?
Can these be left open or grounded? If possible, I would prefer not to have to use additional resistors.
Thanks, Piers

If the TPS65073 touch screen controller is not used, connect
AD_IN1 (TSX1) to ground
AD_IN2 (TSX2) to ground
AD_IN3 (TSY1) to ground
AD_IN4 (TSY2) to ground
Bypass and INT_LDO still need their recommended capacitor connected to maintain stability of the internal power supplies.
