DC-DC converters are widely used today to reduce or convert DC supply voltage levels. In many cases, their use depends on the application and the characteristics of the DC power source. The R2S8-0515/P is a DC-DC converter designed to convert a voltage level from a range of 12-72V DC to 12V, 15V or 24V DC with an adjustable output current. The intended applications for this product are embedded systems, industrial automation, electrical and electronic equipment, AC/DC adapters, uninterruptible power systems, communication systems, automotive electronics, LED lighting and so on.

Working Principle

The R2S8-0515/P follows the standard buck converter topology. It supports both synchronous and asynchronous rectification. Buck converters are so-named because they operate on a concept of “bucketing” the voltage down to a lower level. To do this, the converter switches the input DC voltage in a controlled fashion which reduces the peak voltage level, but increases the current. In the case of the R2S8-0515/P, the input voltage range is from 10V to 36V, but the output voltage is adjustable from 12V to 24V.

The R2S8-0515/P follows a step-down topology, meaning that the incoming voltage is stepped down to one that is a specific magnitude below it. To achieve this, the converter uses an inductor and a capacitor as an energy storage unit to stabilize the output voltage. The voltage is applied to the DC input terminal and then passes through the converter’s converter switch. As it is switched on and off, the voltage is stepped down and the current is stabilized.

The output voltage is then regulated by an internal voltage feedback loop to ensure that the output voltage remains close to the desired one. The output voltage can be adjusted between 12V and 24V by changing the value of the feedback resistor. The output current is also adjustable by changing the value of the output current limit resistor. The maximum output current is up to 5.0A.

The R2S8-0515/P also features over voltage, over current, and over temperature protection. This protects the converter and its components from being damaged due to excessive input voltage, excessive output current, and/or high operating temperatures. Additionally, the converter is protected from short circuits thanks to its over current protection.

The R2S8-0515/P is well suited for applications requiring high power conversion efficiency, high reliability, and excellent power stability. The converter has a wide operating temperature range, low output ripple, and fast transient response. Additionally, the converter offers adjustable output voltage or current, which makes it very versatile. It is especially popular for use in automotive electronics, LED Lighting applications, and other customized solutions.
