: Most available models are "idealized." They may not perfectly capture thermal drift or the exact propagation delays found in the physical silicon. Rating: 4.5/5
Since an official model is unavailable, engineers widely use the macro-model originally optimized by independent developers (such as Bordodynov). You can find stable functional netlists on platforms like GitHub's Power Inverter Repositories . tl494 ltspice
