WEBENCH® Tools/LM25117-Q1: LM25117-Q1 passive components

Part Number: LM25117-Q1

Tool/software: WEBENCH® Design Tools

Hello All, 

I am using LM25117-Q1, in my application for that purpose I had a question regarding the WEBENCH Design. 

Once I enter the values for Vout, Iout which I need in my design before launching webench. After I launch WEBENCH, i get a schematic view with all components value. Is it to be kept same irrespective of other components used in the system. 

Bill of materials shows all the components with different values and price. I wish to place an order of LM25117-Q1 and so I need to know if I can go ahead with all the other passive components and order them as they are in the schematic as I have time limit and the components will take a while to arrive 

Thanks

    I believe you can follow the component values on webench. As for inductor and capacitor make sure you order the part with the same saturation current and capacitor with the same voltage rating.

    Thanks

    Hi, 

    So changing input voltages, and varying current will not have anything to do with change in any passive components values. I entered the design parameters , Iout - 6A and Vin - 12V to 40V .... I downloaded the Bill of Materials and pdf, I got your point  of capacitors with voltage rating, but similar to what ? I mean ordering the same company products used in the design by TI will it help ? 

    Also another question is , Can I built a circuit using LM25117-Q1, with few other components using webench (eg- other SMPS IC, its passive circuitry) all together in a single webench design.?
