DC-DC converters are electronic devices used to convert direct current electricity or DC energy from one voltage level to another. The R1S-1209/HP-R DC-DC converter is one of these converters, designed to give reliable and efficient power conversion when utilized in commercial, industrial, and military applications, making it a popular choice for designers in these market segments. This article will explore the application field, the working principle, and some of the primary features of the R1S-1209/HP-R.

Introduction

The R1S-1209/HP-R is a 10A, single-output, regulated, and isolated DC-DC converter that offers high input voltage, low output voltage, and low ripple. It offers a wide range of input voltage options with a wide input range between 4.5v and 16V, and a nominal output voltage of 12V.

The typical applications of this product include power management of discrete semiconductor components, local power supply for telecommunications systems, airlines, and telecom core networks. It can also be used to power embedded systems such as industrial robots, home and business automation systems, office automation systems, as well as a vast array of other electronic applications.

Working Principle

The R1S-1209/HP-R DC-DC converter operates on the buck-boost principle. This type of converter can be utilized when the input voltage is higher than the output voltage or lower than the output voltage. The buck-boost topology utilizes two inductors connected in series and two switches that direct the current flow. It also utilizes a controller IC that controls when the two switches are turned on and off.

In buck-boost converters, the input and output voltages are completely independent and can be adjusted by varying the duty cycle of the two switches and controlling the current flow. Depending on the input voltage, the controller IC will automatically select which of the two inductors is used for the required output voltage. The R1S-1209/HP-R is rectified to yield a constant output voltage, regardless of the input voltage.

Features

The R1S-1209/HP-R features many advanced features designed to improve its performance and reliability in various applications. The converter features a Transient Response Rate of 850mS, a low ripple (100mV), and high efficiency of up to 87%. It also offers an adjustable output voltage range between 4.5v and 16V.

Additionally, the R1S-1209/HP-R is designed for environmental protection. Its EMC filter for EMI/RFI provides immunity from power line interference, and its MIC (MIL-STD-704) provides protection against voltage spikes. Furthermore, the converter is equipped with an OVP (Overload Protection) to prevent the device from being damaged due to excessive current or voltage input.

Finally, the R1S-1209/HP-R is RoHS compliant, and can be customized in terms of output voltage and other parameters to meet your specific requirements.

Conclusion

The R1S-1209/HP-R is a 10A, single-output, regulated, and isolated DC-DC converter offering a wide range of applications including power management of discrete semiconductor components, local power supply for telecommunications systems, airlines, and telecom core networks. It features a wide input voltage range, low ripple, and high efficiency. It is designed for environmental protection and is compliant with RoHS. The converter thus offers reliability and efficiency when utilized in commercial, industrial, and military applications.
