DC DC Converters

DC-DC converters are electronic devices that convert the voltage or current of a direct current (DC) source to an alternative direct current. This device is used mainly in power supplies and portable electronic equipment, where it provides the necessary step-up or step-down voltage or current in order to efficiently power the load.

The V72B12T250BN3 is a type of DC-DC converter. It is a two-stage, high efficiency, non-isolated DC-DC buck module for VGA and LCD flat panel applications. It is designed for environments with high vibration and shock levels, and has a system efficiency of up to 95%. It has an input voltage range of 9-48V, and an output voltage range of 3.3-12V.

Application Field

The V72B12T250BN3 is ideal for applications where high efficiency, reliability and full compliance for both environmental and safety standards are required. It is ideal for powering VGA and LCD flat panel displays in kiosks, medical equipments, unmanned remote monitoring systems, industrial displays in transportation and other tough environments.

Working Principle

The V72B12T250BN3 is a two-stage non-isolated buck converter that consists of a power switch, a low-voltage current sense resistor, an inductor, a bulk capacitor, a controller IC, and a low-side output capacitor. In the first stage of the buck converter, the power switch is activated and cycles, controlling the flow of current from the input to the output, creating a magnetic field around the inductor. In the second stage, the current is smoothed and regulated by the controller IC and the output capacitor. This regulates the output voltage of the converter, providing a steady, efficient flow to the output.

The V72B12T250BN3 is a high efficiency DC-DC converter, ideal for powering VGA and LCD flat panel displays in tough environments. Its two-stage design ensures efficient operation over a wide voltage range, making it suitable for a variety of applications.
