Hello,
My customer wants to use LP55281 with an external supply. Can FB be left floating? Is Cout still needed?
From the datasheet: "Feedback break protection — prevents uncontrolled operation if FB pin gets disconnected."
Thanks,
Michael

Hi Michael,
Please take a look at this forum: LP55281 External Supply instead of Boost output
You could leave FB and SW pins floating and turn off register settings respectively.
