AM2432: Want to Reduce FBs

Tool/software:

Hi,

In the AM243x EVM Schematic, some 1.8V analog supplies are distributed through some FBs, but the customer want to reduce the number of FBs.

Is it possible ?

For example, is it no problem if they design VDDA_PLL0, VDDA_PLL1, and VDDA_PLL2 using one FB ?

Or they should use each FB for each supply ?

Could you tell them the reason why ?

Thanks and regards,

Hideaki
