DC/DC Converters

DC/DC converters are devices used to convert electric power from one DC voltage to another, either higher or lower. They are relatively simple electronic components that offer a wide range of power management solutions. And among DC/DC converters, VE-B6K-MW-S devices are of particular importance.

VE-B6K-MW-S Application Field and Working Principle

VE-B6K-MW-S devices are small and compact switched-mode power converters specifically designed for harsh environments, having a wide working temperature range from -40℃ to +85℃. In commercial and industrial systems, they are suitable for various applications such as ISDN, power back-up, electromechanical control, telecommunication, and computer system power supply.

VE-B6K-MW-S circuit is based on a traditional DC to DC converter topology, with a control IC. The design consists of two main sub-circuits: the power sub-circuit and control sub-circuit. The power sub-circuit, which includes an inductor, diode, and MOSFET, forms a step-down/step-up converter that can convert a large-range input voltage within the accuracy tolerance of the power supply.

The control sub-circuit is the brain of the device, consisting of a control IC and other small components. This sub-circuit is used to control the power MOSFET and thus provides the current duty cycle of the converter. The duty cycle of the MOSFET is regulated by the control circuitry and is what allows the converter to achieve a smooth voltage output over a wide range of input voltages.

VE-B6K-MW-S devices provide proportional voltage or current output across all output levels with high accuracy (±1%). They offer programmable features such as built-in soft-start, digital dimming, over voltage protection, over current protection, and power-good signal. The built-in under voltage lockout feature prevents the device from initiating operation during severe input voltage drops.

In summary, VE-B6K-MW-S devices are suitable for a wide range of applications that require an efficient, reliable, and cost-effective DC/DC converter solution. They are especially suitable for use in harsh environments, such as those found in industrial and vehicular applications. The device\'s high accuracy, simple design, and wide input and output voltage ranges make it a viable solution for a variety of power conversion needs.
