Other Parts Discussed in Thread: UCC27536, TPS40210
I get good results running a simulation of the UCC23513 as a stand alone part.
I can add a driven N-MOSFET also with good results. However, this in only the case when the source of the MOSFET is referenced to GND.
If I float the MOSFET above ground, providing Vcc via a bootstrapped supply referenced to Vss, the simulation fails.
I believe this is at least partly the result of the use of node 0 in nested sub circuits. Node 0 is always assumed by Spice to be ground.
My experience is the use of node 0 a model prevents it from operating in a floating application. I would love to be wrong here!
Please, tell me how to use your model in this fashion, or tell me the UCC23513, contrary to all indications in the data sheet, is not capable of operating in a floating configuration.
On the other hand, if the model is defective, please fix it! I'm nearing the point of doing a proof of performance board and I'm still in the dark regarding this part.
