You can save the following code as TL494.sub and include it in your schematic.

Always verify the model’s dead-time behavior by plotting the output against the ramp. tl494 ltspice

This is classic in switching converters. You can save the following code as TL494

: The LTspice Group contains extensive collections of models and example schematics. build a prototype

Try simulating a TL494-based boost converter with slope compensation, or add a second error amplifier to implement overcurrent protection. Once the waveforms look clean, build a prototype, and you’ll find that the real circuit behaves remarkably close to your LTspice simulation.
