DC DC converters provide a reliable, efficient, and economic solution for a wide range of applications across different industries. The SUS31212B is a DC DC converter designed for applications requiring a steady power source, such as industrial automation, or for powering motor drivers. In this article, we will examine the main application field and basic working principle of the SUS31212B.

The SUS31212B is a DC DC converter designed for use in applications requiring a steady, reliable power source. It has a wide input voltage range of 4.5 to 18 V, and can output a voltage between 5 and 24 V. It has a maximum output current of 3 A and an efficiency of 85%, which makes it ideal for most modern industrial automation equipment. Additionally, it features over temperature and reverse-polarity protection, further enhancing its capability to maintain a reliable and steady power.

The SUS31212B features a terminal-to-terminal architecture, allowing for easy integration into a system. The input terminals accept an unregulated input voltage up to a maximum of 18 V, while the output terminals deliver a regulated output. It also has an embedded intelligent protection circuit that prevents over temperature and reverse-polarity conditions. Furthermore, the SUS31212B has a wide switching frequency range between 20 and 200 kHz, making it suitable for a variety of applications.

The basic working principle of the SUS31212B is quite straightforward. It works by taking an unregulated, non-adjustable input voltage and converting it to an adjustable, regulated voltage. This is done by using a switching transistor that acts as a switch for converting the input voltage to an output voltage. This switching transistor acts as a bridge between the input voltage and the output voltage. When the output voltage is lower than the input voltage, the switching transistor is switched off, which in turn changes the polarity of the output voltage. Thus, a steady, constant voltage is achieved.

In addition, the SUS31212B employs an advanced active-clamp circuitry to reduce switching losses and minimize heat generation. This also helps to improve both the efficiency and the reliability of the SUS31212B. Furthermore, it also helps reduce the total harmonics distortion (THD) below 10%.

In conclusion, the SUS31212B is a DC DC converter designed for applications requiring a steady and reliable power source. It is ideal for most modern industrial automation equipment and motor drivers, as it offers a wide input voltage range, steady output voltage, and has a high efficiency of 85%. Furthermore, it features an embedded intelligent protection circuit that helps to ensure that the unit remains safe and reliable. Lastly, it also employs an advanced active-clamp circuitry, which helps minimize switching losses and further improve both efficiency and reliability.
