I am trying to design a working principle scheme to step-down the input voltage from 24Vdc ---> different low voltages (1.8 V, 1 V, 1.5 V, 3.3 V with ripples ~ 1%).

Could you kindly explain me the the pro and cons of considering a single step-down converter (replicated for all the requested lines)?

...or differently, you suggest me to implement two different steps (e.g. 24V --> 5V and then 5V ---> other lines?)?

What are the pro and cons of this latter solution?

Thank you very much,

GM
