DC–DC converters are electronic devices that convert a DC input into a DC output with a different voltage. DC–DC converters are widely used in electronic devices such as computers, mobile devices, and industrial equipment where either a higher or a lower voltage is required than the one supplied by the main source.

VE-B4K-EW-S is a DC–DC converter produced by EPCOS. The product name stands for Variable Input, Buck, 4.5V to 15V, Enhanced WhipSaw® Technology. This converter is designed to quickly and precisely convert an input voltage of 4.5V to 15V into a regulated output voltage between 0.8V and 7V.

Application Field

VE-B4K-EW-S DC–DC converters are designed for single-output, high current applications that require efficiency levels of up to 95 percent, such as:

• Industrial applications
• Telecom systems
• Medical equipment
• Voltage regulation of 12V industrial power supplies
• IoT edge computing
• Networking devices

Working Principle

VE-B4K-EW-S DC–DC converters use EPCOS\' Enhanced WhipSaw® technology to provide a very rapid voltage pressure, along with an ultra-fast transient response. This ensures precise output voltage regulation with very low output ripple and noise while providing improved efficiency over traditional non-EPCOS DC–DC converters.

Additionally, the integrated SMBus or PMBus control interface allows the converters to be programmed and monitored remotely, making them suitable for various industrial, IOT, and networking applications. The converters also feature a synchronizable switch frequency of up to 2.2 MHz, which enables the integration of multiple converters for higher current applications, while also reducing EMI.

VE-B4K-EW-S DC–DC converters are designed to operate over a temperature range of -40ºC to +85ºC, making them suitable for a number of industrial and other applications.

In summary, VE-B4K-EW-S DC–DC converters are designed for applications requiring very precise output voltage regulation, with fast transient response, low output ripple and noise, and high efficiency. The converters use EPCOS\' Enhanced WhipSaw® technology, as well as an integral SMBus or PMBus control interface and optional synchronizable switch frequency of up to 2.2 MHz.
