As a small switching power supply, DC-DC has been widely used in electronic design because of its small size and strong performance. It is increasingly widely used in communication, network, industrial control, railway, military and other fields. Many system designers have realized that the correct and reasonable selection of DC/DC manufacturer supply can save the trouble in power supply design and debugging, and focus on their own fields. This can not only improve the reliability and design level of the overall system, but also shorten the development cycle of the entire product. How to select DC/DC vehicle voltage booster/buck power supply module correctly and reasonably?

In fact, when selecting DC-DC DC vehicle voltage booster/buck power supply module, we have many choices. In addition to the basic voltage conversion function, we also have the following aspects to consider.

Rated power: It is generally recommended that the actual power used should be 30-80% of the rated power of the vehicle voltage booster/buck power supply module (the specific proportion is also related to other factors, which will be mentioned later), In this power range, all aspects of the manufacturer supply performance are relatively full, stable and reliable. Too light load will waste resources, while too heavy load will be detrimental to temperature rise and reliability. All manufacturer supplies have a certain overload capacity.

Packaging forms: There are various packaging forms of vehicle voltage booster/buck power supply module, including those conforming to international standards and non-standard ones. For the same company's products, there are different packages for the same power product, and different powers for the same package. How to choose the packaging form?
