This is probably not news to power supply engineers but I just discovered that TI has a whole-ass interactive power supply designer for their ICs where you just give it what SMPS controller you want, desired operating parameters and what to optimise for and it spits out schematic, BOM, reference PCB, efficiency curves, noise figures, etc.
So adding an SMPS to your board is apparently as easy as just pasting their design in and you're good to go
