DC DC Converters: VI-B61-CU-B1 Application Field and Working Principle

DC DC converter refers to the electronic circuit used to convert direct current (DC) from one voltage level to other. In particular, the VI-B61-CU-B1 is one of the most popular small, high-efficiency DC DC converters today. This converter operates in a wide range of input voltage to provide output with the desired voltage and current for a wide range of applications, from automotive and consumer electronics to industrial, medical and energy applications.

Applications of VI-B61-CU-B1 DC DC Converter

The VI-B61-CU-B1 DC DC converter has a wide range of application. In automotive applications, it can be used to power electric systems, such as electric windows, windshield wipers, power steering, lights, ignition and fan speed controls. It can also be used to power LCDs and LEDs used in automotive navigation and infotainment systems. In consumer electronics applications, it can be used to power cellular phones, PDAs, MP3 players, digital cameras, tablets and laptop computers. It can also be used in industrial applications, such as laboratory, manufacturing and automation. Additionally, it can be used in medical devices, such as blood analyzers, heart rate monitors and implantable devices, just to mention a few.

Working Principle of VI-B61-CU-B1 DC DC Converter

The VI-B61-CU-B1 DC DC converter is built with set of linear and digital controllers on board. By combining the two controllers, the converter is able to precisely and efficiently convert the input voltage to any desirable output voltage. To regulate the output voltage the linear controller constantly monitors the voltage reading from the output bus and adjusts the current supply accordingly. This is achieved through a feedback mechanism, where the output voltage is sensed and compared against the programmed voltage that constitutes the reference for the output voltage value.When the output voltage is higher than the programmed value, the linear controller will reduce the current supply to the output bus. Conversely, when the output voltage is lower than the programmed value, the linear controller will increase the current supply to the output bus. On the other hand, the digital controllers are used to measure and maintain the desired load current according to data from the output bus. During power-on or overload conditions that cause large changes in the load current, the digital controller activates a large current flow, allowing more current for the output bus and at the same time providing protection for the entire system.

Conclusion

The VI-B61-CU-B1 DC DC converter is a small, high-efficiency, off-line converter designed for use in a wide range of applications, from automotive to consumer electronics, industrial and medical. Its built-in linear and digital controllers enable the device to precisely and efficiently convert input voltage to the desired output voltage, providing a reliable power source to the connected devices.
