We have been using the TPS63020 in our designs for several years, but are now updating the PCB. Previously we had VINA connected to VIN, but I notice the data sheet was modified 3/19 to remove the VIN/VINA connection. FIgure 3 shows an internal resistor between VIN and VINA. There is no mention of the resistor, or the relationship of VINA to VIN. Sould we now drop the connection between VIN and VINA (using the internal resistor and an external filter capacitor), put an external (what value?) resistor between VIN and VINA, or how should these now be handled?
