FX3 power supply

[KeWa_2323766]

We are using FX3 with a hub. Hub can power the downstream VBUS with 12VDC. There is 12V/5V DC/DC converter on the FX3 board. So, the power network would be like the following,

FX3 Vbus:  supplied by 5V from the DC/DC convert,

FX3 3.3V, 1.8V, 1.2V : supplied by 5V to 3.3V ,5V to 1.8V, 5V to 1.2V DC/DC converter. 

Will this power supply topology have any problem with FX3? 

I can't load block diagram picture using this new forum system  by the way. It would be easy to understand the power network with diagram. 

Thanks,
