I have three switching regulators. A 12V, 5V(green box), and 48V(purple box). The plan is to supply both regulators through -/+12vout pours.
If I am trying to minimize board size while also minimizing EMI, what is the best strategy for laying out these regulators?
If I pack the components as much as I can, what will the consequences be?
A professional perspective on how power should be routed to the green and purple regulators would be highly appreciated. Lastly, any criticism of current design is extremely valuable to me.
*Board stack up is 6 layers with L2 & L5 as GND Layers.
