DC-DC converters allow the user to manipulate the voltage of their power supply and create a wide range of voltage levels using just one or two transformers. The VI-24T-MV-F1 is one such DC-DC converter from Vicor Corporation that has the ability to step down voltage from 24V to a range of voltages from 1.2V to 15V depending on the application. It is a fixed voltage step down converter and is capable of providing an output current of up to 110A.

This particular advanced DC-DC converter is designed to offer reliable operations, proven performance, high power density and efficiency, and an excellent mean time between failure (MTBF). This makes it ideal for applications such as power supplies for portable equipment, computers, medical equipment, instrumentation, and telecommunications.

The VI-24T-MV-F1 ensures high operating efficiency due to its 0.05 ohm on-resistance throughout the input voltage range. This results in a lower component count and greater thermal management, leading to cooler operation. The design of this DC-DC converter also reduces the cost of ownership significantly since it eliminates the need for a separate power supply and control circuitry.

The VI-24T-MV-F1 comes with a variety of power management features including programmable soft-start, current mode control, and overvoltage protection. It can also be combined with other Vicor converters such as the VITA 48.2-compliant VI-Chip and the PCIe-compliant VITA 67.3-compliant VI Chip. All these features allow the converter to be customized for any specific application to ensure greater performance and reliability.

The working principle of the VI-24T-MV-F1 is fairly simple and straightforward. Firstly, it functions as a voltage regulator which involves reducing the input voltage to the required level. This is done using a transformer that is coupled with an inductor to create an output voltage. This transformer is connected to a dual N-FETs switch or to a regulator transistor. This switch or transistor is then controlled by a Pulse Width Modulation (PWM) controller. The purpose of the controller is to direct the switch or transistor to open and close periodically, converting the output voltage.

Finally, a filter is used to remove unwanted noise created by the switch opening and closing. This filtering ensures a clean voltage output that is free from disturbances. The entire process is repeated as the PWM controller keeps operating, resulting in a consistent output voltage at the desired level. Additionally, the converter also monitors robustness and adjusts its working frequency to counter any disturbances in the input voltage.

The VI-24T-MV-F1 is an advanced DC-DC converter that has been designed to offer reliable operations, proven performance, and a long lifespan in various applications. Its high efficiency and low component count allow for an excellent cost of ownership without compromising on the quality of the output power. Additionally, its PWM controller and robust design make it capable of resisting disturbances in the input voltage, ensuring higher system reliability. Therefore, it is the ideal product for applications such as portable equipment, computers, medical equipment, instrumentation, and telecommunications.
