DC to DC converters, commonly known as DC-DC converters, is a power conversion device used to convert a direct current (DC) from one voltage level to another voltage level. A variety of DC-DC converters are available, each designed to operate in specific application fields and with different working principles. In this article, we specifically analyse the features, application field and working principle of the VI-J02-CZ-F3 DC-DC converter.

The VI-J02-CZ-F3 is a non-isolated buck-type DC to DC converter. It is designed to operate within an input voltage range of 4.5 to 35VDC and generate single and dual output voltages. It features a super low quiescent current consumption of 250μA, fast transient and full load efficiency of 84%, load regulation of ±2%, and current limiting, overload, thermal shutdown and short circuit protection.

The VI-J02-CZ-F3 DC to DC converter is suitable for a wide variety of applications, including telecommunications, automotives, industrial control, monitoring systems, inverters, and many other applications requiring a reliable power source. Its wide 4:1 input range and low quiescent current consumption makes it particularly attractive to systems with large power consumption but limited power source.

The working principle of the VI-J02-CZ-F3 DC to DC converter is relatively simple. It utilises a p-channel MOSFET transistor as the main active switch and regulating element. The MOSFET is controlled by a dedicated controller IC, and operates as an on-off switch. When it is on, current is passed through the inductor, generating an increase in voltage. When it is off, the voltage level is maintained by the capacitor. By controlling the switching frequency of the MOSFET, the DC to DC converter can accurately regulate the output voltage and therefore convert the input DC current into the desired output voltage.

In summary, the VI-J02-CZ-F3 DC-DC converter is a powerful, reliable and economical power conversion device suitable for a wide variety of applications. It utilises a basic but effective working principle involving an on-off switch to accurately regulate the output voltage. With its super low quiescent current consumption and wide input voltage range, it is particularly attractive for applications with large power consumption but limited power source.
