In this tutorial, we are demonstrating a project of a 24 V to 12 V converter. The schematic underneath can be utilized to change over 24 V DC to 12 V DC. These kinds of circuits are likewise called “DC to DC converters.” You can step down 24 V DC to 12 V with the assistance of voltage regulator ICs.
7812 is a “12 V Voltage Regulator” that confines the voltage output to 12 V and draws a 12 V controlled power supply. The 7812 is the most well-known, as its managed 12-volt power gives a helpful power source to most “TTL segments.” 7812 is a progression of 78XX voltage regulators. For ICs inside the family, the xx is supplanted with two digits, showing the yield voltage.

24V to 12V DC to DC Converter Circuit
Working Explanation
The schematic that appeared in circuit diagram 1 is utilizing an IC, which is named “LM7812.” LM7812 is a 12 V 1.5 A fixed output voltage regulator IC. You can likewise utilize different ICs for this reason like LM317T which is a “1.5 A adjustable voltage regulator IC” that appeared in the second circuit diagram; the ideal output voltage can be acquired by setting an appropriate resistor value for R1. For getting 12 V from LM317, you can utilize a 2.1 K resistor for R1. In the event that you have more current necessities, at that point, you can utilize the circuit that appeared in the third schematic, utilizing the LM338 IC, which is a “5 A adjustable voltage regulator IC.”
Applications and Uses
24V to 12V converter is a step-down voltage converter. It is used in applications where we need to convert the voltage from a higher value to a lower value.
