I used WEBENCH to design a Vin 23-25V with Vout -18V @3A. It came up with a solution using a LM5116 controller.
The design ref number is 2168835/7. However, when I try to run the simulation as a new design it says no designs are available. This concerns me as I have already designed this circuit into a prototype product and I am now thinking it won't work.
