DC-DC converters are electronic power suppliers used in a variety of applications and the R2D-2405/H is one such type authorized for medium current level applications. It has a high input voltage range of 18 to 65V DC, with the output voltage scalable up to 9V. The pairing of this particular DC-DC converter makes use of a buck topology, allowing for the boosting of voltage when a load is activated, while also lowering the amount of energy dissipated through the output of the unit in comparison to what would be typical of a linear regulator.

The working principle of the R2D-2405/H can be broken down into two stages; switching and regulating. Through the combination of these two stages, it is able to convert the input voltage level and alter it as required. To begin with, the switching process requires power MOSFETs, activated by a controller, to switch from a high voltage state to a low voltage state, causing the input voltage level to be dropped and the output voltage to be raised in the process. The two power MOSFETs connected to the input and output ports of the buck converter are responsible for this function.

Once the switching process is finished, the DC-DC converter then moves into the regulating stage. During this time, the inductor is held at a certain potential, meaning that the voltage and current values on both the input and output ports are at a constant level. The inductor plays a key role in this process as it stops the current from immediately rising and was only able to do so when the voltage and current levels remain consistent. As the voltage and current needs to remain constant for the inductor to effectively work, the controller needs to switch the power MOSFETs off and on rapidly to constantly read and adjust the input and output signals.

The R2D-2405/H DC-DC converter can be found in a variety of applications due to its practicality and efficiency. As well as commercial arrangements such as power supplies, LED drivers and motion controllers, it is widely used in the automotive industry whereby it helps to regulate various engine systems and infotainment boxes. Additionally, medical users are able to make use of the DC-DC converter for generating clean power in order to power medical instruments and diagnostic equipment.

In conclusion, the R2D-2405/H DC-DC converter is a versatile unit, authorized for medium current level applications. Its pairing of the buck topology and two stage switching process allows it to convert the input voltage into a usable level, whilst also conserving power and energy. The efficiency of the unit makes it suitable for various applications, a few of which include automotive, commercial and medical purposes.
