Hi What will the output of the box be used for? If low phase noise is an objective, then one needs to be pretty careful about power supply noise. If low phase noise is not a “need” in this case, then (good) switchers can be used for everything.
What’s a “good” switcher? You want one that is reliable ( = does not catch fire on a regular basis). You also want to get the noise down into the 10 mv p-p range. That generally means filtering the output a bit. Past that the usual requirements of line / load regulation and efficiency come into play.
