V72A12E400B

DC-DC Converters are used to convert direct current (DC) voltages from one level to another. As a type of power converter, they can be used to increase or decrease voltage, as well as to provide power isolation. This is particularly useful in applications where energy efficiency and circuit protection are important. The V72A12E400B is a DC to DC Converter module from Vicor, designed to provide superior efficiency and ripple performance for mission-critical or powerful applications like UPS systems and telecom equipment.

V72A12E400B Features

The V72A12E400B is a slim-profile converter module, measuring just 2.36 in x 1.59 in x 0.55 in (60 mm x 40.6 mm x 14.0 mm). It has a wide input voltage range of 9.0 – 75 VDC, and a continuous output power of 400W. This level of power output is achieved with high-efficiency performance of up to 89% and low power-sapping ripple with a typical value of 12 mV. The module also has an adjustable output voltage from 0.9 – 55V, and a high power density of 296 W/in³. It also features short-circuit protection, undervoltage and overvoltage protection, over-temperature protection, and a variety of other safeguards to protect your equipment and assure reliable operation.

V72A12E400B Application fields

The V72A12E400B\'s slim form factor and high power density makes it an ideal choice for mission-critical applications where space and power savings are key considerations. It is commonly used in industrial equipment, telecom equipment, power supplies, distributed power systems, computers, and other applications where space is at a premium. Additionally, its superior efficiency and low ripple levels make it ideal for advanced applications such as battery-backed systems, battery chargers, and uninterruptible power supplies (UPS).

V72A12E400B Working Principles

The V72A12E400B DC to DC Converter is based on a switching regulator topology. Inside, a DC-to-DC power stage consists of a switching transistor, an inductor energy storage device, a diode, and a capacitor. As the switching transistor turns on and off, the voltage across the inductor changes, releasing stored energy into the load. The voltage waveforms in the circuit are further regulated by a control circuit, allowing for efficient power transfer from input to output. The input and output voltages are configurable through different combinations of induction coils, capacitor and other components.

In its 9-75VDC input range, the V72A12E400B works with Vin1 > Vout+1V. If Vin1 is not greater than Vout+1V, the regulation loop is not complete, resulting in no output. This DC to DC Converter\'s flow control system is based on the principle of power loss detection, with temperature signal generation and temperature detection feedback to the MOSFET gate driver circuit. In this way, it can minimize power losses and further improve the module\'s overall efficiency.

Final Thoughts

The V72A12E400B from Vicor is a powerful and reliable DC to DC Converter module, designed for space-constrained applications where power efficiency and circuit protection are of paramount importance. With its wide voltage input range and various protections, the V72A12E400B is an excellent choice for mission-critical or powerful applications.
