Description

The TL494 PWM Adjustable Pulse Generator Module is a high-performance PWM control module designed for generating precise and stable pulse width modulation signals. Built around the TL494 control IC, it provides adjustable frequency (500Hz–100kHz) and duty cycle, allowing users to fine-tune pulse characteristics for various applications. Operating within a 7V–40V DC input range and delivering a 5V PWM output, it ensures compatibility with microcontrollers, sensors, and electronic circuits. This module supports push-pull or single-ended configurations, features dead-time adjustment, and includes an internal 5V voltage reference for reliable performance. Compact and efficient, the TL494 PWM Generator is widely used in motor speed control, switching power supplies, signal processing, and industrial automation systems, providing consistent and flexible signal generation for advanced electronic designs.
