LM5117: Preferred solution for 20-48Vin, ~20Vout /12A

Hi team,

I'm searching for a buck controller for the application of 20-48Vin to around 20V output @12A. I noticed LM5117 is the proposed on after filtering. 

May I get your help to propose some more options here for customer selection please? If possible add the calculation tool for customer parameter selection. 

Back ground is investigation on PD EPR 48V/5A 1st level buck down to ~20V system voltage for a PC,

Thanks for your help,

Max
