DC DC converters are widely used in everyday applications. A popular DC-DC converter is the VE-20J-CX-F3. This device is a high frequency isolated DC-DC power converter, designed to meet demanding requirements for high efficiency, power density and small footprint. In this article, we will discuss the application field and working principle of the VE-20J-CX-F3.

The VE-20J-CX-F3 converter is primarily used in applications that require high isolation, such as AC/DC and DC/DC conversion. It is designed to convert mains power to low voltage DC. The device can also be used to convert DC voltage from one level to another. This makes it an ideal choice for DC/DC UPS systems, isolated power supply applications, and other power conversion requirements.

The VE-20J-CX-F3 has an operating frequency range of 100-320 kHz, providing a flexible solution for different applications. The device has a power efficiency of up to 98%, with a peak power density of 10 watts per cubic centimeter. It also features soft-switching technology, providing a very efficient solution with reduced electromagnetic interference (EMI).

The working principle of the VE-20J-CX-F3 converters is based on flyback topology. This topology works by using an inductor that stores energy while the switch is closed, and outputs the stored energy when the switch is opened. The device also uses an opto-isolation circuit, which provides electrical isolation between the output and input stages. This prevents any interference from the input signal to the output, providing reliable operation and good performance.

The VE-20J-CX-F3 also features built-in current limiting, protection from overload and short-circuit, and built-in thermal protection. These features make the device suitable for a wide range of applications. The device is also available in an industry-standard 4-pin form factor, making it easy to integrate into existing systems.

In conclusion, the VE-20J-CX-F3 is a high-frequency isolated DC-DC converter that is designed for a wide range of applications, including AC/DC power conversion, DC/DC UPS systems, and other power conversion needs. It has a power efficiency of up to 98%, with a peak power density of 10 watts per cubic centimeter. The device uses flyback topology and features built-in protection, making it a reliable and efficient solution for a variety of applications.
