DC-DC converters are ideal solutions to support a wide range of applications, from industrial, automotive and consumer electronics to single-board computers and medical devices. One such DC-DC converter is the DVQ0135V2NBSC, which is a monolithic high-efficiency synchronous buck converter with an extended output voltage range. This article will provide an overview of the DVQ0135V2NBSC’s application fields and working principle.

Application Field

The DVQ0135V2NBSC is a single-chip DC-DC converter designed for applications which require up to 600mA output current from an input voltage of 4.75V to 28V. It is ideally suited for automotive, industrial, medical and other demanding applications, such as the following:

• Portable and mobile electronics
• Body area networks (BAN)
• Industrial control systems
• Data communication system components
• Power systems for IoT, wearable and autonomous devices

The device is capable of driving up to 12V from 3.3V or 5V on the input side, making it well suited for applications where high-current, efficient power conversion is required. Furthermore, the on-board protection features, such as over-current and over-temperature protection, provide robustness and safety for a variety of different systems.

Working Principle

The DVQ0135V2NBSC utilizes a synchronous buck converter topology, which is an efficient and cost-effective solution for converting a higher input voltage to a lower output voltage at a constant current. The device consists of two power switches, an inductor and a freewheeling diode. The two power switches alternately turn ON and OFF at a certain frequency, creating an average output voltage proportional to the duty ratio of the switching frequency. The device also includes integrated reverse current protection and other features to protect the converter and the load it supplies.

The DVQ0135V2NBSC has a high-efficiency circuit design that minimizes power dissipation and maximizes power transfer to the load. Its integrated low-noise linear regulator feature ensures the converter runs with little noise, making it suitable for a wide range of noise-sensitive applications. It also features a power-saving mode that reduces power consumption and extends the battery life of mobile applications.

Conclusion

The DVQ0135V2NBSC is a robust and high-efficiency DC-DC synchronous buck converter, ideal for applications which require up to 600mA output current from an input voltage of 4.75V to 28V. With its wide range of integrated protection features, low noise linear regulator and power-saving mode, the DVQ0135V2NBSC is an ideal solution for automotive, industrial, medical and other demanding applications.
