Many times we have the requirements of 24V to 12V converter. The circuits shown below can be used to convert 24V DC to 12V DC. These type of circuits are also called DC to DC converters. You can step down 24V DC to 12V with the help of voltage regulators ICs. The circuit shown in figure 1 is using


a LM7812 IC, which is a 12 volt 1.5A fixed  output voltage regulator IC. You can also use other ICs for this purpose like LM317T which is a 1.5A adjustable voltage regulator IC shown in figure 2, the desired output voltage can be obtained by placing a suitable resistor value for R1. For getting 12V from LM317 you can use a 2.1K resistor for R1. If you have more current requirements then you can use the circuit shown in figure 3, using LM338 IC which is a 5A adjustable voltage regulator.
