Tl494 Ltspice !full! Jun 2026

: Ensure this pin is tied to GND for maximum duty cycle or biased with a voltage to set a specific dead-time, otherwise, the PWM may not start [8, 15]. Wait for Stabilization

: This pin provides a 0V to 3.3V input to limit maximum duty cycle. In simulation, grounding this pin allows for the maximum 45% (per output) duty cycle. Output Control (Pin 13) : Tie to GND : Single-ended operation (parallel outputs). tl494 ltspice

The TL494 is a classic fixed‑frequency PWM controller IC. LTspice does include it by default, but you can add a third‑party model. : Ensure this pin is tied to GND

Simulating the in LTspice is a common task for power electronics, but it requires specific third-party models because Texas Instruments does not provide an official SPICE model [13, 19, 27]. Finding and Installing the Model Since there is no built-in component, you must source a (subcircuit) or (schematic-based) model from the community: LTspice Groups.io LTspice Groups.io Output Control (Pin 13) : Tie to GND
