DC-DC converters are electrical devices that can convert direct current (DC) from one DC voltage levels to another. The DP4660-9RG is a special DC-DC converter, designed for high efficiency, low noise, and highly reliable operation. This article will provide an overview of the application field and the working principle of the DP4660-9RG.

Application Field of the DP4660-9RG

The DP4660-9RG is a high-performance DC-DC converter designed for fast charging applications, such as portable electronics, robots, energy storage systems, navigation systems, and more. The device features high efficiency of up to 92%, low self-consumption, and high compatibility with low voltage battery system designs. As such, the DP4660-9RG is well suited for automotive and industrial applications.

It is also suitable for various medical and military applications. The DP4660-9RG is a novel high efficiency synchronous rectifying DC-DC converter with excellent performance. It is designed to provide a high-performance platform for low noise, high efficiency, and reliable operation in wide temperature ranges.

Working Principle of the DP4660-9RG

The DP4660-9RG is a synchronous rectifying DC-DC converter that works by using two integrated variable frequency oscillators to drive a full-bridge switch. The oscillator-interlocked synchronous rectifying circuit ensures low power dissipation and low electromagnetic interference (EMI). When the switch is duty-cycling current, current is actively controlled by the synchronous rectifier.

To ensure device stability, the DP4660-9RG also includes a current limiter and over-temperature protection. The over-temperature is monitored by a temperature sensor, and the current limiter will take over from the synchronous rectifier when the current reaches a certain level. This ensures low ripple, high accuracy, and stable operation.

The frequency of the DP4660-9RG is adjustable from 4Hz to 20kHz, allowing for a wide range of adaptability to different applications. This is important, as different applications require different output characteristics. The frequency can be adjusted through a built-in frequency, voltage, or current regulator.

Conclusion

The DP4660-9RG is a special DC-DC converter designed for high efficiency, low noise, and highly reliable operation. It is suitable for a wide range of applications, including those in the automotive, industrial, medical, and military sectors. The device features an adjustable frequency, a synchronous rectifying circuit, current limiter, and over-temperature protection, allowing for reliable and stable operation in different environments.
