We just want to verify we can indeed use REFOUT on the TPS51200 part as the 0.75V VREF output for a single DDR3 device pinned off of a Spartan 6 memory controller. What confused us a litte is the TMS320C6678_EVM dev kit schematic which chooses not to use the REFOUT pin for VREF and instead uses a resistor divider. We used a simple resistor divider in our previous design but since we are now adding the TPS51200 part on our PCB we would like to use the REFOUT if possible.
