Other Parts Discussed in Thread: TPS65220, TPS51206, TPS22965
My customer is considering to use AM64x with TPS65219.
Then they are checking " Powering the AM64x with the TPS65220 or TPS65219 PMIC" applicqation note (SLVAFE9).
Then they have some questions. There is the below block diagram on P16.
PVIN of TPS51206 is described as "From 3.3V-buck output".
But the PMIC doesn't have 3.3V output in this case.
Where this 3.3V comes from? Is it VSYS(3.3V) or TPS22965 output?
Similar to Q1. Where the PVIN(3.3V) of TLV5518P comes from?
LDO1 and LDO2 outputs are not connected in this figure.
What does it mean? Are both outputs floating?
