DC-DC converters are commonly used in many areas of practical application, especially in the power electronics industry. Used in vehicles, home appliances, commercial electrical systems, and many other applications, DC-DC converters are essential devices used to transfer electrical power from one DC supply to another. The most commonly used type of DC-DC converter is the VI-B5M-IU-F2, which is a high-efficiency, isolated, buck converter.

VI-B5M-IU-F2 is a series of isolated, step-down DC-DC converters based on the Texas Instruments C2000 digital control system. It provides a high level of efficiency and high-frequency switching with extremely low losing. The VI-B5M-IU-F2 is versatile, with its ability to accept a variety of input voltages while simultaneously providing a constant output voltage according to the user’s requirements.

In terms of function, the VI-B5M-IU-F2 is a high-efficiency, step-down, isolated buck converter. The converter offers a wide input voltage range of 9V to 48V, and a programmable output voltage range of 0.8V to 5V at up to 150A in continuous mode. This makes it perfect for applications needing high-current power transmission from a 12V or 24V cell battery, as is used in electric vehicles.

The VI-B5M-IU-F2 is built around a full-bridge MOSFET buck converter topology. This buck converter works by first using a power stage to step down the input voltage, and then the controller filters and regulates the output current for the desired output voltage. The power stage consists of two input capacitors that store the incoming energy, two synchronous rectifying MOSFETs that control the voltage conversion, and two output capacitor that filters and smooths out any remaining ripples.

The C2000 digital control system is what makes the VI-B5M-IU-F2 so versatile and reliable. It is an ARM Cortex-M type processor that allows a secure, flexible and reliable control over the various parameters of the converter. This includes protection against over-temperature, under-voltage, over-voltage, over-current and short-circuit of optional external devices. The digital control system also offers users the ability to adjust the amount of ripple on the output, as well as frequency synchronization and burst mode operation.

The VI-B5M-IU-F2 is an ideal solution for applications needing an isolated, high-efficiency DC-DC converter that maintains a consistent output voltage. Its wide input voltage range, large current capacity, and versatile digital control system make it the perfect choice for a variety of power conversion needs.
