As an unofficial but widely used component, the TL494 requires a .sub file. 1 = 1IN+ 2 = 1IN- 3 =
: Press T on your keyboard to add comments or SPICE directives [6].
The frequency of the internal oscillator is set by the classic formula: The frequency of the internal oscillator is set
Add a generic component (like dip16 ) and rename it to match the subcircuit name in the file (e.g., TL494 ).
Based on community experience, here’s a summary of best practices:
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 .
