DC-DC Converters are electrical power conversion devices used to convert a current or voltage from one DC value to another. The DC-DC converters transform low voltage DC sources, such as batteries, into higher voltage DC sources, such as that needed by electronics. The REC3-4809DRW/H/B/SMD is one such type of DC-DC converter.

Application Field

This type of converter is most widely used in military, aerospace, and automotive electronics. It can also be used in industrial, medical, communications, audio, and lighting applications. It is designed to work with standard H or B voltage packages, as well as SMD technology. It also meets military standards for shock and vibration, and has been proven to be reliable in harsh environments.

Working Principle

The REC3-4809DRW/H/B/SMD DC-DC Converter uses a synchronous rectifier topology to control voltage and current levels. This type of rectifier is a bidirectional device that can be used to convert AC signals or non-sync pulses into DC, as well as to produce constant level of DC voltage upon input pulses. At the output stage, this type of converter uses a buck converter together with a high efficiency switch. A PWM controller is used to determine the switching times and thus control the output voltage. The converter also includes an input filter and an output filter to reduce noise and ripple that may be generated by the switching waves. In addition, the converter is typically equipped with external components such as inductors, capacitors, and other elements to ensure optimum performance.

Conclusion

The REC3-4809DRW/H/B/SMD DC-DC Converter is a reliable and efficient device that is suitable for military, aerospace, automotive, industrial, medical, communications, audio, and lighting applications. It works on the principle of using a synchronous rectifier topology in combination with a buck converter and PWM controller to control voltage and current level, while filtering out any generated noise or ripple.
