DC/DC converters are becoming increasingly popular in a variety of applications. PT5821N is one of the leading DC/DC converters in the market, and its applications and working principles are explained in this article.

No matter in what kind of application environment, PT5821N can provide ultra-wide input voltage range of 6V-60V and selectable output voltage range of 0.59-18V. It also provides protection against overvoltage, undervoltage, short circuit, and thermal overload. It also provides an optional heating and cooling function. With these features, PT5821N can offer high efficiency, high power density, and excellent cost performance.

For the working principle of the PT5821N, the high-voltage input is first rectified, then processed by a transformer, and then converted into a low-voltage output. The main components of the transformer are a primary coil, a secondary coil, and a magnetic core. The transformer helps to increase or decrease the voltage according to the turns ratio of the two electrodes. Another crucial component is FETs, which are used to control the efficiency of the power supply. Besides, the control circuit of the PT5821N has an MCU for precise monitoring and control.

As mentioned above, PT5821N can offer high efficiency, high density, and excellent cost performance. Therefore, it has been widely used in harsh environments, such as automobile, Aerospace, geological survey, railway transportation, industrial control, and military/aerospace, etc. For example, it is very suitable for such small power supplies as cameras, automotive entertainment, and navigation power supply. What\'s more, due to its low power consumption, it has been widely adopted in medical equipment, small precision instrumentation, and industrial wireless products.

In conclusion, PT5821N is a popular DC/DC converter in the market. With its great features and advantages, it can satisfy various applications in harsh environment. It has a wide input voltage range and various output voltage options. The transformer and FETs are the two main components for its working principle. Moreover, PT5821N can offer high efficiency, high power density, and excellent cost performance.
