Can a DC-DC step down converter be built?
In conclusion, the step-down (Buck) converter circuit had been successfully built using the LM7809 positive voltage regulator. Based on the measurements that are performed, the step- down circuit was able to convert the higher DC input voltage (11V-17V) to 9V DC output voltage.
Is there a way to step down from 24VDC to 12VDC?

Are there any downsides to a DC-DC converter?
The main downside to DC-DC converters compared to a linear regulator is that the output will have some amount of AC voltage ripple riding on the DC output. The amount of ripple depends on the quality of the output filtering.
Why is a DC-DC converter better than a linear regulator?
Power dissipation in a DC-DC converter tends to be more related to the amount of current being supplied and less related to how much voltage drop there is between the input and output of the device. The efficiency of DC-DC converters is typically much better than the equivalent linear regulator circuit.

Which is the industry’s largest DC / DC switching regulator?
We have the industry’s largest and most diverse portfolio of DC/DC buck modules. With integrated FETs and inductor, power modules simplify your power supply design process and get you to market faster. Our comprehensive portfolio of DC/DC buck converters covers an input voltage range of 1.3 V to 100 V and output current up to 40 A.
How is a DC voltage converted to a lower voltage?
Converting a higher DC voltage to a lower one is a common requirement found in most electronic circuits. This might be something like converting the 12V from a battery down to 5V in order to power an electronic board. A portion of that 5V may be further converted down to 3.3V to drive a lower voltage portion of the circuit.
Do you need a buck converter for 3.3 V?
A buck converter is probably appropriate for making the 3.3 V from 9 V. The voltage drop is larger and the current probably higher than the moisture meter. For example, is you need 100 mA at 3.3 V, a linear regulator would draw the same 100 mA from the battery.
Is it possible to convert 9V to 5V?
The current drain on the battery will only be (388 mW)/ (9 V) = 43 mA. Note that this is less than half of the battery drain resulting from using a linear regulator. Yes, it is possible using resistors.
What does a step down voltage regulator do?
Voltage regulator is one type of electrical regulators that provides the ability to maintain the voltage at the constant level. It is also capable of stepping-up, stepping-down, and inverting the input voltage supply.
How does a DC to DC converter work?
Let’s look at each of these different types of converters and how they operate: Buck converter is a DC to DC converter that is producing a voltage that has been stepped down (reduced) from the input voltage. As such, you can use it to power a lower voltage devices from a higher voltage source.
What are the disadvantages of a DC to DC converter?
Their disadvantages are price, noise and design complexity. There are many different types of DC to DC converters depending on the application they can be used for. Four of the main kinds include: buck converter, boost converter, buck boost converter, and SEPIC converter.
What makes a DC to DC converter isolation?
A DC to DC converter with isolation will typically feature an isolation transformer present between the input and output stages. This tends to be especially useful when the input voltage level and the output voltage level are largely different from each other.
