DC DC Converters

VI-J3T-IZ-S application field and working principle

DC DC converters, also known as DC to DC converters, are electronic devices that convert a steady direct current (DC) voltage into another DC voltage. To achieve this, they allow the output voltage to be increased or decreased. This comes in handy when trying to interface different types of DC electrical systems. DC DC converters are used across a variety of industries, including renewable energy, automotive, aerospace, and consumer electronics. Their features and performance characteristics vary, depending on the application.

The VI-J3T-IZ-S DC DC converter is an innovative solution for a range of power supplies. It is the only DC DC converter on the market to use reverse-polarity PWM technology. This feature provides improved input/output and efficiency ratios, as well as superior transient response. The architecture includes three stages of voltage amplification, built-in protection circuits, and a patented current mode control system.

The VI-J3T-IZ-S is designed to convert a variety of input voltage levels including 6V to 36V, and provides a selectable output voltage range from 2.5V to 28V. Thanks to its high efficiency (up to 95%) and low-quiescent current (2mA), the VI-J3T-IZ-S can provide up to 60W of power. Additionally, the converter features a wide input voltage range operating temperature, which has been tested from -40°C to +105°C.

The working principle of the VI-J3T-IZ-S DC DC converter is based on switched-mode power supply technology. The unit includes two power MOSFETs connected in series between the input and output, with an inductor in between. As the MOSFETs are alternatively switched on and off, an AC voltage is induced in the inductor. This alternating voltage is then rectified through the output rectifier and filtered capacitor, which results in a DC output. This process is repeated every switching cycle in order to maintain the correct output voltage.

The VI-J3T-IZ-S DC DC converter is ideal for a range of applications such as powering satellite communication systems, renewable energy systems, and other industrial equipment. It features high-performance, transient protection, adjustable current limits, and low switching noise. This DC DC converter provides an efficient, low-cost solution to meet your specific power supply requirements.
