Tl494 Circuit Diagram Link
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. The Core Architecture
Below are three practical schematics. Component values are included for common frequencies (typically 50kHz to 100kHz). tl494 circuit diagram
