Step-down voltage converters and line stabilizers – differences and basic use

The step-down converters you see above are a great alternative to linear stabilizers, but they can have many more practical possibilities. The differences between voltage step-down converters and linear stabilizers are noticeable in terms of the results that their use brings. Stabilizers are used to maintain a constant output voltage. For this purpose, they use other elements, most often transistors. The control circuit monitors the output voltage. When necessary, it corrects the voltage and maintains the state without disturbance of the power supply. Linear stabilizers have a lot of advantages. The most important are, above all, low purchase costs and a simple mechanism of operation. However, these are not effective devices. As a result of the operation of linear stabilizers, excess voltage is converted into heat. Moreover, it is not possible to change the voltage level. If these drawbacks are crucial for the project, then the stabilizers should be replaced with other devices. And this is where the step-down voltage converters in this category appear on the horizon!

How do step-down voltage converters work?

Step-down converters (also known as buck converters) are a kind of a DC-to-DC power converters. The principle of operation in that case is quite simple. Step-down converters can down voltage from its input to its output. Operation is unidirectional - always decreasing voltage, but you can find out that there are some bidirectional devices too (we have them in our store). Anyway, voltage step-down converters are a kind of typical switch-mode device. They will regulate the level of current voltage making sure it is not too high.

These types of devices are not free from any problems. The design involves the use of a powered coil. Therefore, a step-down converter requires several other elements to work properly: a good coil or several coils, a switch, capacitors and a driver (most often an integrated circuit).

Voltage step-down converters and their use

Step-down converters are used to convert direct voltage. Lowering the voltage level in a given circuit is possible with very small power losses. The energy efficiency of step-down converters is at a very high level. Therefore, these types of step-down converters are perfect for systems powered by batteries. Remember that while stabilizers convert excess voltage into heat, the converters presented in this category - thanks to their high efficiency - heat up practically imperceptibly. As a rule, raising the voltage is less efficient than lowering it, so it is better to have a high supply voltage and lower it than too low and raise it. Step-down converters are used in many different applications - both industrial and amateur. In Botland, this category is very popular due to the fact that we often need this type of components to create our own electronic projects.
