DC-DC converters are devices that transfer direct current (DC) power from one source to another. Specifically, the V375B5C150BS2 is a type of non-isolated synchronous buck converter that converts a wide input voltage range to a low output voltage range. It is commonly used in applications such as medical electronics, industrial and automotive electronics, battery charging, and telecom power supplies. This article will discuss the application field and working principle of the V375B5C150BS2 converter.

Applications

The V375B5C150BS2 DC-DC converter is designed to offer a wide input voltage range of up to 350V, while still providing an output voltage of 5V. This makes it ideal for use in applications requiring a high input voltage, such as automotive electronics, as well as low-power applications needing a low output voltage. Furthermore, the converter offers up to 150W of power and efficiency ranging from 88-96%. This makes it suitable for applications such as medical electronics, battery chargers, and telecom power supplies.

The converter also offers open-loop and closed-loop current sharing capabilities, allowing multiple units to be connected in parallel in applications requiring higher power. This makes the converter suitable for high-power applications, such as factory automation equipment and industrial equipment.

Working Principle

The V375B5C150BS2 DC-DC converter is a non-isolated synchronous buck converter. This means that the output voltage is determined by the ratio of the input voltage to the output voltage, and is regulated using a feedback loop. The converter consists of three main components: an inductor, a diode, and a MOSFET switch. The inductor is used to store the energy, while the diode and MOSFET switch are used to control the flow of current.

When the switch is open, the inductor stores energy and the voltage across the inductor increases. When the switch is closed, the inductor releases energy and the voltage across the inductor decreases. The diode prevents the current from flowing in the opposite direction, while the MOSFET regulates the current. The output voltage is regulated by the duty cycle of the MOSFET switch.

Conclusion

The V375B5C150BS2 is a non-isolated synchronous buck DC-DC converter of up to 150W. Its wide input voltage range and low output voltage range makes it ideal for use in automotive, medical, industrial, telecom, and battery charging applications. The converter also offers open-loop and closed-loop current sharing capabilities for high-power applications. The converter is regulated by the duty cycle of a MOSFET switch, and consists of an inductor, a diode, and the MOSFET switch.
