Hi! In this post, I’m going to share the Buck converter Proteus library model. This model is based on the MC34063 converter. The MC34063 is loved for its simplicity and effectiveness in various DC-DC conversion tasks, making it a favorite among designers and engineers in many electronic applications.
MC34063: The Heart of the Buck Converter Model
The MC34063 is a versatile DC-DC converter IC that can be used for step-up (boost), step-down (buck), and voltage inverter applications. Originally developed by Motorola (now ON Semiconductor), it’s popular for its flexibility, ease of use, and cost-effectiveness. But because it’s so popular and widely used, other semiconductor manufacturers, like Texas Instruments, also make compatible versions of this IC.
You can also download the datasheet from their websites, or you can get it directly by clicking here. I’ve included links to the datasheets from both manufacturers.
Buck Converter Proteus Library Model
This library model is based on the typical application example of the step-down converter provided in the datasheet.
If you want to build the circuit, you can use the schematic from the datasheet. To finish designing the converter, you’ll also need to add some external components like inductors, capacitors, diodes, and resistors.
The MC34063 is set up as a step-down (buck) converter, designed to lower the input voltage (Vin) to a reduced output voltage (Vout). In this case, it takes a 12V to 25V input and steps it down to 5V. The output current limit is 500 mA.
