Hello!
I guess this is not for Eval2 but for the other boards?
My understanding is that SMPS1200A400 is a 4 quadrant PS, thus not subjected to power supply pumping
This is already included in the 1ET400A

Maybe simplifying your design by suppressing redundant functions a bit will allow a cleaner layout .
1. SMPS1200A400 Output Voltage Vaux are +20.5V -20.5V , I use the TPS7A4700 TPS7A43300 regulated to +15V, -15V, Eval2 asking the 15V input .
2. this idea come from ergo at #87
