WEBENCH® Tools/LM5005: LM5005 as inverting buck boost

Part Number: LM5005

Tool/software: WEBENCH® Design Tools

Hello Team,

there seems to be a bug in Webench when I simulate LM5005 as inverting buck boost. Webench selected Rramp with 0.56Ohm in the new version which is wrong.

When simulating exactly the same circuit with the old flash based Webench version Rramp is selected with 107kOhm which is in line with the data sheet equation 5, page 13. 

Thanks and Best Regards,

Hans
