DC-DC converters, also known as Buck converters, are voltage regulators that take a high-voltage input voltage and convert it into an adjustable lower voltage output. They are single-ended primary-inductor converters (SEPICs). The VI-B1K-MY-F4 is a novel, fully integrated Buck converter module, featuring high-efficiency, high power, and extruded aluminum construction for enhanced heat dissipation. This module features a maximum input power of 1300 W at 12 V input and can generate a wide range of output voltage between 0.6V – 20V at a maximum output current of 40A. It also offers a wide range of current detection and integrated protections, like input overvoltage, input undervoltage, output current foldback, temperature shut down, and short-circuit protection.

The VI-B1K-MY-F4 is a highly-efficient buck converter with a current-mode control scheme. It is designed to be able to regulate output voltage and current accurately while achieving improved transient load response. The working principle of current-mode control is to sense the output current and adjust the duty cycle of the switch accordingly. This type of control allows for fast response and better control of the output voltage, making it ideal for high-performance applications. The VI-B1K-MY-F4 utilizes a two-phase interleaved topology that allows it to efficiently and precisely regulate voltage and current even at ultra-low load levels by dynamically distributing the load between its two phases.

The VI-B1K-MY-F4 is ideal for applications such as powering servers, networking, communications, point-of-load (POL) and power online double-conversion (POD) architectures. It can be used to reliably power and regulate a wide range of DC voltage rails for microprocessors, memories, FPGAs and ASICs. This module is suitable for industry and telecom applications, data centers, HPC clusters, storage systems and distributed power systems.

The VI-B1K-MY-F4 features a wide range of protection features to protect it from faults or overvoltage conditions. It can detect over-voltage, under-voltage, over-temperature, input undervoltage, output current fold-back, and short-circuit protection. Its integrated protection features help to reduce the risk of damage to sensitive components and protect the module from short-circuit and over-power conditions.

The VI-B1K-MY-F4 is an effective and reliable DC-DC converter module designed to provide reliable power and adjustable voltage rails in a wide range of applications. It utilizes current-mode control to efficiently regulate voltage and current, even at ultra-low load levels, while its integrated protections help to protect the module from faults or overvoltage conditions. This module is well-suited for servicing industry and telecom applications, data centers, HPC clusters, storage systems and distributed power systems.
