TL494 Circuit Diagram: A Comprehensive Guide

Diagram 1: Basic PWM Generator (Test Rig)

Before building a power supply, build this simple test circuit to verify your TL494 works. It outputs complementary square waves without feedback.

Sets the operating frequency (up to 300kHz) using just one external resistor and capacitor. Dual Error Amplifiers: tl494 circuit diagram

TL494 Circuit Diagram: Pinout and Configuration

The TL494 is equivalent to the following devices: TL494 Circuit Diagram: A Comprehensive Guide Diagram 1:

• Switching power supplies
• Motor control
• Lighting systems
• DC-DC converters

In this example, the TL494 is used to control the output voltage of a switching power supply. The circuit consists of:

Inverter Circuits: In push-pull mode, the TL494 can drive two MOSFETs to oscillate a transformer, converting low-voltage DC to high-voltage AC or DC. Design Tips In this example, the TL494 is used to

Output Control (Pin 13): If high, enables alternate output; if low, single-ended output.
