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 control in the on-board DCDC 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 boost/buck voltage power supply for vehicle air conditioning correctly and reasonably?
In fact, when selecting DC-DC DC boost/buck voltage power supply for vehicle air conditioning, 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 boost/buck voltage power supply for vehicle air conditioning (the specific proportion is also related to other factors, which will be mentioned later), In this power range, all aspects of the control in the on-board DCDC 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 control in the on-board DCDC supplies have a certain overload capacity.
Packaging forms: There are various packaging forms of boost/buck voltage power supply for vehicle air conditioning, 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?
