Part Number: TPS56221
Dear support member.
My customer used TPS56221 and LM10011.
I have a question.
（Question1）
In the combination of TPS56221 and LM10011,
Is the TPS56221 VIN and the LM10011 VDD another power supply?
Because
The power supply is shared in the circuit diagrams described in the data sheet etc, there are many cases, I would like to confirm just in case.
（Question2）
If in the case of another power supply,
Is there an oreder of rise sequence?
Best regard.
Bob Lee.
