Hi Haroon,

We are wondering what modifications LM5176EVM-HP needs for 48Vin / 48Vout ?

Is using CSD18532Q5B for all power stage FET enough?

thank you

Hi Nicholas,

Well, you would need to go through the BOM and see if the capacitors are rated for these voltages and what about your current, check fi the inductor is rated for those values, you can use the LM5176 calculator tool to check what current values you will get at your inductor for this.

As for the FETs, well the voltage rating of the FETs is 60V and for 48V it should be ok , but again I would double check using the calculator tool

BR,

Haroon
