We will power our Am3335X board with TPS65910.
I checked some ref.designs and data sheets, but remained some doubts.
1) What means for VAUX33 for TPS65910 "default OFF 3V3"
Some rails have "default ON". In timing chart (SWCU093B) I can't see difference.
between default OFF and default ON rails (I am talking about 3V3 rails)
2) In SWCU093B Ti suggests connect VAUX33 to VDDA3V3P (Usb), but in reference designs
VDDA3V3P is connect to other 3V3 rails
From timing in SWCU093B, I concluded that all three 3V3 rails (VAUX2, VMMC, VAUX33) contemporary rise
so I can use any, but this "default OFF" creates mu doubt. If I use VAUX33 should I after via software enable it ?
Thank in advance
