In section "2 Overview",it says "Power for the XIO2001 EVM and any PCI add-in card connected to the EVM is provided or derived from
the standard voltages provided on the PCI Express connector. Power for the 3.3-V rail is provided directly from the add-in connector, 5-V and 12-V is provided from the IDE power connector..."
According to the above words,3.3-V,5-V and 12-V rails should be all availble to the full design ,but convertion from 3.3-V to 5-V rail exists in the design(through the use of LT1370),why? 5-V rail is not available from IDE?
And also,it seems that there is an error with LT1370's sig --VC and Vin. The two sigs should be exchanged,I think.
