Using a behavioral subcircuit model for the TL494 in LTspice allows engineers to simulate complex PWM control scenarios accurately. By following the proper setup for the oscillator and feedback loops, you can effectively use LTspice to validate your switching regulator designs before prototyping. If you're working on a specific design, I can help you: for a target frequency. Draft a specific .subckt for your LTspice schematic. Troubleshoot feedback loop stability in your simulation.
Since you requested a "good paper," I have structured this response as a technical application note. It covers the operating theory of the TL494, a guide to modeling it in LTspice, and a practical design example. tl494 ltspice
However, designing a power supply on paper is not enough. Modern engineering demands verification. Enter —the powerful, free simulation tool from Analog Devices. Combining the TL494 with LTSpice allows you to debug feedback loops, analyze switching waveforms, and optimize component selection without risking blown MOSFETs or burning resistors.

Output Stage Logic & Dead Time
You can verify PWM logic, oscillator frequency, and feedback loops without damaging components. Draft a specific
