For a given topology (CM or VM, buck, boost, flyback), open up the sample circuit. These BASSO models are relatively easy to use. Recently a customer looking for a Linear Technologies SMPS controller (not in the DB) was successfully able to use a corresponding PWMCM BASSO model in lieu of the actual mfg SPICE model as many of these are propietary or encrypted. The sample I included swapped out the BASSO model for the UC3842 model. Many of sample circuits in the topologies shown have corresponding SMPS controller ICs models with parametric values that allow you to match the specifications closely with the manufacturer's IC specifications. I suggest that for Switch Mode Power Controllers that you also reference the SMPS samples (File -> Open Samples -> SMPS).
Hello - attached is the UC3842 model you are looking for in v10.1 in a flyback topology (modified from existing SMPS samples).
