| Error | Likely cause | Fix | |-------|--------------|-----| | Unknown subcircuit | Missing .lib directive or wrong filename | Add .lib TL494.sub | | Floating node | Unconnected input pins | Tie unused inputs to GND or VREF via 10k | | No oscillation | CT/RT missing or DTC > 3V | Set DTC ≤ 0.5V, check CT/RT values | | Output always high/low | Feedback pin (3) not driven | Connect to error amp output or voltage source | | Convergence error | Steep edges, missing cap | Add 1nF from outputs to GND, use uic or startup | First, create this file as TL494

Since the TL494 is not a native component in the LTspice library , you must import a third-party model to begin. 🛠️ Step 1: Acquiring the TL494 Model 🛠️ Step 1: Acquiring the TL494 Model
