Hello readers! I hope you are doing well. Today, we are going to explore the MC34063 buck converter library for Proteus. An MC34063 buck converter is a type of DC-DC power converter that steps down the high voltage to the low voltage. It’s a popular device to get lower DC volts because it provides a stable output. By default, Proteus software does not have the buck converter; therefore, I designed the library for the simulation of the projects with this converter. In this tutorial, I’ll discuss the basic introduction to Buck Converter and Proteus library installation, and will also share the most basic simulation to see how it works.
The library installation process in Proteus is straightforward. To install the Buck converter follow the steps given next:
MC34063 Buck Converter for Proteus
Note:
Now, when the Proteus library folder has MC34063 Buck Converter, you have to start or restart the Proteus software to load all the libraries.
As discussed before, it takes the higher voltage DC as input and provides lower DC input as output, so the input pins +VIN and -VIN should be connected with the positive and negative input terminals. On the other hand, get the output from +VOUT and -VOUT terminals.
Let’s test the buck converter in a simple circuit. Follow the steps to see the output:
Go to terminal mode from the left side of the screen and add the power terminal to +VIN and the ground terminal to -VIN.
Double-click the power terminal and change its value to 20V.
Now, go to instrument mode to choose the AC voltmeter and connect it with the +VOUT and -VOUT.
The project must look like the following:
Push the play button to see the result.
As you can see, the input voltage is 20V at the +VIN pin, but the output pins have 5.03 volts. That proves the Buck Converter library is useful for the simulation of projects.
The same project is given in the zip file that you have downloaded for the Buck Converter library. I hope you liked the library and tutorial. If you need more help, you can ask in the comment section.
