Understanding the TL494 IC: A Versatile PWM Controller
The TL494 is a highly popular pulse-width modulation (PWM) controller IC developed by Texas Instruments. It's widely used in switch-mode power supplies (SMPS), inverters, DC-DC converters, and motor control circuits due to its flexibility and reliability. Let's break down its key features, pinout, and applications.
Using SG3525 PWM Controller Detailed Explanation
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few.
