Analyze what should be considered for the selection of DCDC power supply module

In fact, our country has hundreds or even hundreds of power supply module R&D and production companies, usually small companies and private companies, so this data can show that the market competitiveness of power supply modules is not very good. Large, and the industry concentration is relatively low. Moreover, the market share of the top ten power module manufacturers in this market is also very low.

In fact, most of the international brands are biased, and our domestic brands are relatively few, especially some low-end power module market analysis, this industry is basically in a situation of complete competition. Therefore, in the high-end power supply module market, there is a good corresponding technology, craftsmanship, etc., and the market concentration will be relatively high, so how should I choose a DCDC power module? In fact, in addition to the most basic voltage conversion function, the following points need to be considered:

The first point; its rated power issue

Usually we recommend using a power that is between 30% and 80% of the rated power of the module power supply. It is more appropriate, because the power supply modules within this range will be more stable in each performance. If the load is too light, it will cause a waste of resources. , Too heavy will cause the temperature to be too high, so choose a module power supply with a certain overload capacity.

The second point; the form of encapsulation

There are many kinds of package forms of module power supply, so how to choose the package form? First of all, note that the volume should be reduced as much as possible under certain power conditions, so that more space and functions can be given to other parts of the system. Secondly, we must choose products that comply with international standards, because good compatibility is not limited to only one or two suppliers. Finally, it should be based on its scalability, which can facilitate the expansion and upgrade of the system.
