DC-DC converter represents a wide range of power converters, which are able to change the voltage or current of DC power source. With the increasingly high demands for high output power, efficiency and miniaturization, a new device, VI-J12-EZ-F4, was developed specially for DC-DC converter applications.

VI-J12-EZ-F4 is a medium power (up to 80W) DC/DC impact resistance closed-loop converter. It has the features of simple structure, wide input voltage range, high efficiency, fast transition time, and low cost. The highest 300 VDCDC input voltage and the highest 80 w output power make this converter suitable for high power output applications like aerospace, military, industrial, communication, computer, automotive and electrical etc.

The input and output of the VI-J12-EZ-F4 DC/DC converter is isolated so that the conversion efficiency is high. It provides an output voltage of +12VDC, adjustable from ±10% to ±20%, can be customized for special applications. The typical efficiency is up to 92%, and the switching frequency is up to 1 MHz. The maximum peak current is 10A, and the minimum output ripple voltage is less than 0.1V.

The working principle of VI-J12-EZ-F4 is based on forward converter topology. The input voltage is converted to a higher voltage by a step up transformer, then it is rectified and controlled to give the output voltage. This power converter works in two operation modes, the PWM mode and the pulse frequency modulation (PFM) mode. In the PWM mode, the main switch is turned on and off at a fixed frequency to make the output voltage constant. In the pulse frequency modulation (PFM) mode, the switch is turned on and off to maintain the output voltage. This helps to reduce the power consumption and increase the efficiency of the converter.

The VI-J12-EZ-F4 is designed to operate under a wide temperature range from -40°C to 85°C, making it suitable for a variety of environmental applications and long life duration. The VI-J12-EZ-F4 DC/DC converter also has several protection functions such as overvoltage, overcurrent and short circuit protection, to ensure safety and reliable operation.

In summary, the VI-J12-EZ-F4 DC/DC converter is a versatile device suitable for a range of different applications in aerospace, military, industrial, communication, automotive and electrical industries. It features low power consumption, high efficiency, flexibility and stability. With its excellent performance in many aspects, the VI-J12-EZ-F4 DC/DC converter is one of the best choices for DC/DC power conversion in the market.
