LM5118Q1MH Query

Hi TI Team,

Regarding the LM5118Q1MH Buck-Boost Controller.    

36 to 54.6V @4A.pdf     

57.5V to 58.5 @4A.pdf     

36 to 58V @4A.pdf     


Please find the three types of simulation we did in the webench simulation for the following specification

Our project mainly will work on the input voltage of 58V and when it will be powered off due to a power cut. The main system voltage will be automatically switched to the battery backup voltage for 5 minutes maximum

Battery voltage can't be constant at all times, it will be in the range of 36V to 54.6V. 

So my question is which input voltage do I have to simulate on the webench.

If I am simulating for 36 to 54.6V and 57.5 to 58.5V means, My circuit showing in the tool is similar, But when I am simulating from 36 to 58V, Inductance value becomes too high and I can't able to change the user-preferred frequency also. Kindly help with this
