• LM25085: Design the Buck converter to zero/low loss at 12V In -> 12Vout

  

  Daniel Domurath

  TI Thinks Resolved

  Part Number: LM25085 Hello, For a project of mine the user is allowed to use either a 12V or 24V power adapter. Than I need to regulate the voltage if it's at 24V down to 12V. First I thought about using a normal Buck with NFET but It would be complicated…
