The TL494 is a fixed‑frequency pulse‑width modulation (PWM) control IC, designed for switch‑mode power supplies (SMPS). It includes:

Pin 14 provides a very stable 5.0V output. Use this for your feedback dividers rather than the raw VCC to ensure accuracy. tl494 circuit diagram

fOSC=1.2RT×CTf sub cap O cap S cap C end-sub equals the fraction with numerator 1.2 and denominator cap R sub cap T cross cap C sub cap T end-fraction

By using the TL494 to drive a high-side MOSFET, you can create a highly efficient step-down converter. The chip ensures that even as your battery drains, the output voltage remains exactly where you set it. Pure Sine Wave Inverters I can help calculate the exact component values

To read a , you must first memorize the function of the critical pins.

When designing or reading a schematic based on the TL494, look for these three mandatory functional areas: 1. Voltage Reference Network (VREF) Pin 14 outputs a highly stable 5V reference ( Use this for your feedback dividers rather than
