Boost switching regulators
Step-up and step-down converters are primarily used in order to make some circuit powered with a right and safe voltage. These converters are able to both - increase and decrease - the overall voltage in the circuit, what makes them really useful. While not every devices' voltage level needs to be increased and decreased, there are also slightly more popular devices such as step-up or step-down converters. The step-up, known as boost converter, is the most widely used in the field of non-industrial electronic devices.
There are many different types of this type of device. An example is one of our products that can be found in this category. For example, a DC-DC converter of the step-up / step-down type (lowering or increasing the voltage). The device has a power supply of 3.0 V - 40 V, and the maximum current value is 1.5 A. It is worth adding that the voltage is, of course, regulated. This is a product that every electronics engineer should have in store!
Step-up / step-down convertors – main advantages and drawbacks
Step-up / step-down integrated circuits have definitely more advantages than disadvantages. First of all, they guarantee holistic solutions. They work well with all kinds of electronic circuits. They are commonly used in advanced and simple electronics.
One of the most important advantages of using step-up / step-down converters is their very high energy efficiency. The value of this parameter most often exceeds 90% (which is already a very good result). This is extremely important in battery or accumulator based systems as they must be properly adapted to the rest of the electrical components. Step-up / step-down converters are also characterized by the fact that they have relatively small dimensions. The small weight of these devices is also important. Thanks to the wide input voltage range (from 100 to 240 V), they can be used in all countries of the world, regardless of the voltage standard in a given country. The only disadvantage of step-up / step-down converters is that usually (although it also depends on many factors) they will be more expensive compared to standard step-down and boost converters.
The quality is crucial
Step-up / step-down integrated circuits have a number of advantages. First of all, it is important to be immune to mains interference and short voltage decays. They are produced at a lower cost. They also have built-in short circuit protection. However, for all of its advantages, step-up / step-down converters are something of a double-edged sword. The point is, there is no perfect electronic device either. Such a device - when improperly built, constructed in a wrong way, with a use of low-quality materials - may lead to high frequency interference and cause unstable operation of the entire system and connected devices. As a result, this can even lead to drastic consequences such as damage to individual components. The complicated structure and the number of parts needed for operation influenced the cost of this type of power supplies. However, the introduction of appropriate integrated circuits in the 21st century made it possible to eliminate this problem.
In systems that are powered directly from the mains, the main filter capacitor located downstream of the rectifier circuit can maintain voltage due to no load. Avoid contact with it as this may result in electric shock. Choosing a reputable chip manufacturer and store eliminates the problem of an uncertain product. You do not have to worry about electrolyte spilling from the converter, or even an explosion, which happened in the past with low-quality converters and devices that cooperated with them.
