Introduction to DC DC Converters

DC-DC converters convert direct currents of one voltage into a direct current of another voltage, often higher or lower than the original. DC-DC converters are widely used in electronics industries, particularly in the telecommunication and aerospace sectors. This article will introduce and explain the application field and working principal of the REC3-4815DRWZ/H/B/M/SMD-R.

Application Field of REC3-4815DRWZ/H/B/M/SMD-R

The REC3-4815DRWZ/H/B/M/SMD-R is a radial leaded, coated plastic surface mount DC-DC converter. This converter is widely used in digital cameras, camcorders, electronic communications systems, and industrial/aviation electronics applications. It is ideally suited for these applications due to its high-efficiency, low noise, and high-density measurements.

Working Principle of REC3-4815DRWZ/H/B/M/SMD-R

The REC3-4815DRWZ/H/B/M/SMD-R operates using a switched-mode power supply, in which two transistors are employed to allow energy to be stored in an electrical capacitor before being released. The input voltage is connected to one of the transistors, while the other is used to control the output voltage. Depending on the application, these transistors may be connected in series, parallel, or a combination of the two. The principle behind this lies in the fact that transistors can act as switches, in which they conduct a current when turned on and isolate current when turned off. When the transistors are coupled with filters and transformers, these can be used to compensate for variations in the output voltage or current and provide a regulated voltage or current for the system. The REC3-4815DRWZ/H/B/M/SMD-R converter includes a feedback loop that monitors the output voltage and adjusts the current flowing into the changing circuit, allowing the output voltage to remain constant. As the output voltage is adjusted, this also adjusts the switching frequency of the transistors, which alters the current output of the converter.

Conclusion

The REC3-4815DRWZ/H/B/M/SMD-R is a widely used and popular DC-DC converter that is used for various applications, from digital cameras to industrial electronics. It features a high-efficiency, low noise, and high-density and is equipped with a feedback loop that monitors and adjusts the output voltage, allowing it to remain constant. The converter operates using a switched-mode power supply, which employs two transistors to transfer, store, and release energy while adjusting the switching frequency.
