Hi,
we're planning to use the LM5116 for a non-isolated power supply. After downloading the pspice transient model and starting the simulation in PSPICE version 16.0, I get the following output:

I changed nothing to the original simulation and there seems to be an error in U1. Please advise how to solve this. Thanks in advance.
