LM5149: About the efficiency calculation results using WEBENCH

Part Number: LM5149

Tool/software:

Hello,

I am an FAE at a distributor that handles TI products.
My customer is considering the LM5149, and asked me about the results of an efficiency calculation done on WEBENCH.
I have attached the results.
It seems to be quite efficient even at low currents, but is this a reasonable result?

Best regards,

    Hello Kaji,

    The WEBENCH results are often curve fitted and there maybe errors in the corner cases, at lower currents.  suggest using the calculator spreadsheet in the product folder for a more accurate estimation.  Hope this helps.
