Since finding a perfect SG3525 model is difficult, here's how to create it:
Final Verdict:
If you need quick simulation for a simple SMPS design, a third-party SG3525 library from a trusted site works fine. For production-level verification, consider using LTspice or SIMetrix where an accurate SG3525 model exists.
To confirm you have a better library, run a simple simulation. Do not just drop the part; test its core function.
Circuit Setup:
Expected Output (Oscilloscope):
If your simulation shows a flat line or an error about "SPICE model missing," your library is not better. Return to Step 3.
Even with a better library, users make common mistakes.
