    Hi,

    The model of ucc28v59 should have no convergence issue as it is tested before release. You would have to debug the external circuit to find which causing convergence. I suggest you start with a known circuit such as UCC28C43 simulation circuit from ti.com then replace UCC28C43 with UCC28C59 to start. This way you can find UCC28C59 has no convergence issue and also help you to debug your circuit from a known condition.
