Tl494 Ltspice
The remains one of the most enduring integrated circuits in power electronics. Introduced decades ago, its flexibility makes it a staple for designing switched-mode power supplies (SMPS), DC-DC converters, and inverter topologies. However, prototyping switching controllers in hardware without prior verification often leads to damaged components and lengthy debugging cycles.
Another convenient source is the LTwiki. The “Bordodynov’s Electronics web page” available through the LTwiki main page contains the complete library of TL494 symbols and models. This is regularly cited in engineering forums as the go-to resource for TL494 LTspice models. tl494 ltspice
