Working Principle

The VI-20J-MY DC/DC converter operates on the buck-boost principle, transferring power through a series of controlled switching operations, from an input voltage that may be higher or lower than the desired output voltage. When the input voltage is greater than the desired output voltage, the VI-20J-MY is in buck mode, switching transistor Q1 is turned on, and inductor L1 is energized, and transistor Q2 is turned off. When the input voltage is lower than the desired output voltage, the VI-20J-MY is in boost mode, transistor Q2 is turned on, and inductor L1 is energized, and transistor Q1 is turned off. It also includes a thermal shutdown circuit as a safety feature to protect the converter from over-temperature conditions.

High Efficiency and Low Noise

The VI-20J-MY DC/DC converter is designed to operate at a high efficiency, which means that less of the input power is wasted as heat. Along with its high MTBF, this allows the VI-20J-MY to be a reliable and cost effective solution for demanding industrial and automotive applications. The device also features low noise operation, ensuring that noise-sensitive embedded systems and applications can run without disruption.

Conclusion

The VI-20J-MY DC/DC Converter is a state-of-the-art DC/DC converter that provides reliable, efficient conversion of one DC voltage to another DC voltage. It is capable of accepting input voltages between 4.5 and 350 VDC and providing regulated outputs of up to 5 VDC and 20 watts of power. With its high efficiency, low noise operation, and EMI immunity, the VI-20J-MY is an ideal fit for a variety of applications including automotive, medical, industrial, aviation, and military applications.
