Simulate a load transient to see how the TL494 adjusts the PWM duty cycle to maintain a stable output voltage.

) is much higher (e.g., 13V). While this is fine for logic-level MOSFETs, standard MOSFETs might not fully enhance, leading to inaccurate efficiency results in your simulation. Startup Delays : To speed up your simulation, consider using the tl494 ltspice
