DC-DC converters offer a reliable and effective method of converting direct current (DC) energy into another form. The most common types of DC-DC converters are isolated buck converters, which use an inductor and capacitor to create a voltage step down, a full bridge converter, which is a full bridge rectifier used for AC-DC conversion and a synchronous rectifier, which is used for DC-DC power conversion. The R2S12-2412/HP is a high power isolated DC-DC converter built from an asynchronous buck topology. This converter has a wide input range, features adjustable output, and operates with an efficiency greater than 90%.

With a 12V output, and a maximum power of 24W, this converter can operate out up to 2A under certain conditions. The R2S12-2412/HP features an adjustable output voltage, which can be set from 1V to 11V, as well as a fixed output voltage option. The converter also offers current limiting, short circuit protection, over voltage protection, and over temperature protection. The conversion efficiency is greater than 90%, and the converter can operate in temperatures from -40 to +105 degrees Celsius, with a maximum temperature of 100 degrees Celsius.

Application Field

The R2S12-2412/HP converter is suitable for a variety of applications, including automotive electronics, industrial machinery, and medical equipment. It can be used in applications requiring a wide input voltage range, as well as those requiring adjustable output voltage. Additionally, the converter can be used in applications where small size and low weight are necessary due to its high power density. Its efficiency makes it an ideal choice for applications where energy-saving is a priority.

Working Principle

The R2S12-2412/HP is an asynchronous buck converter, which uses an inductor and a power switch to regulate the voltage and current. The power switch is used to control the energy delivery to the output. When the switch is on, the energy stored in the inductor is released at the output. When the switch is off, the energy stored in the inductor is recirculated back into the input. The inductor also acts to shape the current waveform and limit the current. To ensure the desired output voltage, an external controller is used to adjust the duty cycle of the power switch.

In addition, the converter features an asynchronous periodic reset to ensure that the peak inductor current is predictable. This reset is generated by the controller and lasts until the inductor current grows to its peak value. This reset ensures that the peak current is consistent, independent of input and output voltages.

The R2S12-2412/HP also features an adjustable output voltage, which is regulated by the controller. The output voltage can be adjusted using an external resistor. When the output voltage is adjusted using an external resistor, the duty cycle is adjusted to maintain the desired output voltage, ensuring an efficient and stable operation.

Conclusion

The R2S12-2412/HP is a high power isolated DC-DC converter, which can be used in a variety of applications, including automotive electronics, industrial machinery, and medical equipment. The converter uses an asynchronous buck topology, and provides a wide input range, adjustable output, and operates with a conversion efficiency greater than 90%. Additionally, the converter features an asynchronous periodic reset, to ensure that the peak inductor current is predictable. The adjustable output voltage is regulated by the controller, and is adjusted using an external resistor.
