DC-DC converters are an essential part of power electronics systems, as they can convert electrical energy from one DC voltage level to another. The VE-B4F-EU-S is a 4:1 DC-DC converter with isolated output (i.e. isolated from the input) specifically designed to meet the stringent demands of applications in the medical, telecom and industrial automation industries. This converter offers ultrafast load response, very high efficiency and exceptionally low-output ripple, noise, and crosstalk due to the use of a high-performance, efficient LLC resonant converter topology.

The VE-B4F-EU-S is ideal for applications where power quality is critical, such as medical imaging and telecom. Its novel LLC resonant DC-DC converter architecture provides a very wide 4:1 input voltage range, from 9V to 36V, and can handle peak input current up to 30A. The output is adjustable from 3.3V to 13.2V, with 5V/12V/15V/24V standard outputs available, and a maximum output power of 400W. The high-frequency switching of the LLC topology allows for a very fast load transient response, and allows for a very small size, with a package size that is 43% smaller than an equivalent transformer-isolated topology DC-DC converter.

The VE-B4F-EU-S is controlled by a proprietary digital signal processor (DSP), which is used to monitor the output voltage and adjust it in order to keep it constant, even with changing load conditions. This ensures that the output voltage is kept within the specified range, and minimizes power losses due to light or heavy loads. Additionally, the DSP technology also provides over-temperature and over voltage protection features, which prevent damage to the device and connected components.

The VE-B4F-EU-S can operate in either a continuous current or a constant voltage mode, and is protected against short-circuiting, over-voltage and over-temperature conditions. It has excellent electromagnetic interference (EMI) characteristics due to its low-profile design. The device is also tested and certified to UL, CSA and CE safety standards.

In conclusion, the VE-B4F-EU-S is a an ultra-high performance and reliable DC-DC converter designed for applications in the medical, telecom and industrial automation industries. Its LLC resonant topology offers ultrafast load transient response, very high efficiency and exceptionally low-output ripple, noise and crosstalk for critical applications where power quality is a must. Additionally, its small size allows for easy mounting and integration, and its proprietary DSP technology provides over-temperature and over-voltage protection features, further ensuring safe operation and a long life-time.
