DC/DC converters have become increasingly popular over the years. These devices use an external power source to supply energy to a load circuit. They are commonly used in telecommunications, industrial automation equipment, consumer applications, and power systems such as electric vehicles. One particular type of DC/DC converter, the R2S12-2405/HP-R, is designed for applications where a constant power output is needed over a wide input voltage range. This article will discuss the application field and working principle of the R2S12-2405/HP-R DC/DC converter.

The R2S12-2405/HP-R is a rugged, versatile DC/DC converter that caters to a range of industry needs. It offers a wide 4:1 input voltage range spanning 4 to 16 VDC, and operates up to an output power of 120 W. This makes it well-suited for applications in telematics, offshore drilling, and other rugged environments where high accuracy and stable power are required. Furthermore, the device is engineered with an innovative synchronous rectification and internal MOSFETs that maintain the highest efficiency possible. It also includes an active current limiting protection that steps in when the output voltage exceeds the rated power. This helps protect the device and the connected load from damage due to overcurrent and overtemperature.

The R2S12-2405/HP-R uses a two-phase converter as its topology. This is a highly efficient design that allows for much higher power densities and system size reduction. The device is equipped with two independent DC/DC converter modules, each module comprising of two switching FETs. Each phase contains two dedicated MOSFETs, or channels, in an integrated circuit power switch. Each channel works in the following sequence: Step 1) An input voltage is applied to the transistor gate; Step 2) Current flows through the inductor; Step 3) The gates of the FETs are driven by a voltage derived from the peak current flow, Step 4) The two channels in parallel configuration, increase the power dissipation capability; Step 5) As the output voltage falls during the long pass, the gates of the FET become biased and the FET’s switch off.

The R2S12-2405/HP-R also has an internal voltage feedback loop that is used to regulate the output voltage. This loop reads the output voltage and adjusts the duty cycle, or "width" of the switching edge, in order to regulate the output voltage within a precise range. The device includes cycle-by-cycle current limiting, which helps to protect it from short circuit conditions. An adjustable soft start feature allows users to optimize the system’s power-on sequence. Other helpful features include a power OK indicator LED, overvoltage protection (OVP), and undervoltage protection (UVP).

The R2S12-2405/HP-R is a robust, reliable DC/DC converter that can be used in a variety of applications. It provides high efficiency and features a robust protection package. It is well-suited for industrial applications that require a wide input voltage range and a reliable, stable power output. The device is easy to use, and its wide feature set makes it very versatile and efficient.
