DC-DC Adapters are high frequency power conversion circuits that use high frequency switches and inductors, transformers and capacitors to smooth switching noise into a stable DC voltage. The closed feedback loop maintains a constant voltage output even when the input voltage and output current are changed. At 90% efficiency, they are typically more efficient and smaller than linear regulators.

What are the advantages of using the DC-DC Adapter?
Input voltage range
That is, the UPS allows the variation range of the mains voltage, because the local voltage fluctuation directly affects the operation of the UPS, especially in some areas where the power grid is relatively poor, and the voltage during the day and night is very different. If the UPS is to work 24 hours a day, with such a wide range of changes, it is critical that the UPS works. If it can't work, only turn the battery. In this way, the battery is not used for real power failure. Second, the frequent turning of the battery will affect the life of the battery. If the battery transfer device of the UPS is a relay, the damage to the relay is particularly serious, which greatly increases the failure rate of the UPS.
mains power
The smaller the power supply, the less heat the machine generates, so the machine will continue to project for a long time. In order to use safety, the projector is generally equipped with an overheating protection device.
Noise and Filtering
This indicator needs to be judged intuitively and quantitatively through professional instruments. It is mainly that the 220V AC power is converted into various low-voltage DC power through the filtering and voltage stabilization of the switching power supply. Noise marks the smoothness of the output DC power, and the filter quality is directly related to the output DC power. The level of the AC component, also known as the ripple factor, the smaller the better. At the same time, the capacity and quality of the filter capacitor are also related to the stability of the voltage when the current changes greatly.

In today's super-speed information age, people's lives are inseparable from digital communication products such as mobile phones and computers. However, the battery life of these products is always unsatisfactory. In view of this situation, the DC-DC Adapter is characterized by a multi-functional charger, which is light and easy to carry, beautiful and fashionable, etc. In fact, it is not only suitable for notebooks, but also for many digital products. Be applicable. Anytime, anywhere and in various occasions, as long as there is a power interface, you can charge your notebook, mobile phone, tablet, camera, MP3, MP4, MP5, etc., solving the problem of short notebook power usage time.
