UCC28C40: Pspice problem

Janos nagy

Part Number: UCC28C40

I downloaded and imported the PSPICE model SLUM32.zip of UCC28C40. If I release Pspice it finds that VDD, Vref and RTCT pins are floating dispite tha fact that they are connected in the schematics. So the Pspice does not start because of this failure. How can I solve this problem. Without this chip the simulation works.

Thank your answer, slum519 does not contain file with *.olb extension.

I solved the problem, I added the UCC28C40 to the part list and assigned the lib file to it as global. Now simulation runs. Usage of Pspice sometime is complicated.
