Tl494 Ltspice

We will configure the TL494 for a single-ended output driving a P-Channel MOSFET (a common topology for high-side buck converters using TL494 logic).

When you first open LTspice, you will notice a vast library of components. However, because LTspice is developed by Analog Devices (formerly Linear Technology), the default libraries prioritize Analog Devices products. The TL494, being a Texas Instruments part, is absent from the standard cmp library. Tl494 Ltspice

The TL494 can be successfully simulated in LTspice using a third-party subcircuit. The model reproduces oscillator, duty-cycle limiting, error amplifier regulation, and output switching behavior accurately. This allows designers to test power supply control loops, soft-start, and fault responses before hardware prototyping. We will configure the TL494 for a single-ended

However, while the TL494 is a hardware staple, simulating it can be a hurdle for many engineers and hobbyists. As a legacy part, it is not always included in the default installation libraries of modern simulation software like LTspice. The TL494, being a Texas Instruments part, is
