In addition to the most basic voltage conversion function, there are the following aspects to consider:
1. Rated power
The most important thing to consider about dc-dc power module is its rated power, generally speaking, the rated power of the power module is limited to about 30~80 is the best, mainly because the power module in this range is relatively reliable in terms of performance, and the load is too low, which is easy to waste resources. However, the load is too high for temperature control and stability is not particularly easy to control, although it is said that the power module has a certain load capacity, but it is also recommended not to load for a long time, which will shorten the life of the module, so we need to choose the right power module in the best range and meet their rated power module.
Two, packaging form
dc-dc power module packaging mode has a variety of different countries of the packaging standards are different, of course, non-standard also have, then the choice of packaging form is mainly to consider the following three aspects, one is to determine the power conditions of the case to be as small as possible, because this can provide more space, the second is as far as possible to choose the national standard of the power module, The third is that the power module with scalability should be selected, because it can continue to be upgraded in the case of subsequent system upgrades, rather than being limited by the power module.
