Team,
I did not find indication in the datasheet about using separate supply rail/voltage to power the different VIN pins (VIN1/VIN2/VIN3).
All the example circuit show a single VIN that supply all VIN1/VIN2/VIN3 inputs.
Is it allowed to use different voltage rails to supply VIN1/VIN2/VIN3 as long as they share the same ground?
If yes can you detail the requirements for this?
If no why do we have then named and represented VIN1/VIN2/VIN3 as three distinct inputs rather than a single VIN rail on multiple pins?
Is it for example possible to have the below scheme?
12V on VIN1/VIN2 to generate 5V on LX1 and 3.3V on LX2
re-use the generated 5V: on VIN3 to generate 1V1 on LX3
on LVIN1 to generate a 3V3bis on LOUT1
and re-use the generated 3V3 on LVIN2 to generate 3V0 on LOUT2
I can provide the schematics offline.
Thanks in advance,
Anthony
