Tl494 Ltspice Link

: Models designed for PSPICE (often found in OrCAD libraries) can be imported into LTspice by manually creating a matching schematic symbol. Subcircuit Structure

* Dead Time & PWM Logic (Pin 4) * Dead time voltage effectively offsets the sawtooth floor or clamps the comparator. * If V(4) > Sawtooth, Output is OFF. * Effective PWM comparator: Duty Cycle = (V_saw - V_dead) / V_saw_amp. tl494 ltspice

You can download the official TL494 PSpice model from TI's website. Note that while LTspice can run most PSpice models, some syntax adjustments (like changing ** to ^ ) might be needed in the subcircuit file. : Models designed for PSPICE (often found in
