Tl494 Circuit Diagram Jun 2026

If you are looking to understand or design a circuit using the TL494, this guide breaks down its internal architecture, pin configuration, and two essential circuit diagrams.

is a classic fixed-frequency Pulse Width Modulation (PWM) control integrated circuit (IC) that has served as the backbone for switch-mode power supplies (SMPS) for decades. Its enduring popularity stems from its comprehensive architecture, which integrates all the essential functions for PWM control—oscillator, error amplifiers, dead-time control, and output steering—into a single 16-pin package.
