DC/DC converters are an important type of electronic component, used to convert a direct current (DC) voltage or current into another DC voltage. The REC5-4809SRWZ/H4/C/SMD-R is an example of a buck-boost converter that can be used in a variety of applications. This article covers the application field and working principle of this type of DC/DC converter.

Application Field

The REC5-4809SRWZ/H4/C/SMD-R converter is primarily used in low-power consumer and industrial applications. The input voltage is a wide range (4.5V-130V) and the output voltage is adjustable from 0.5V-72V with an efficiency up to 92%.

The REC5-4809SRWZ/H4/C/SMD-R is capable of supplying up to 1.2A continuous output current or 5A peak current. It is suitable for applications such as the powering of signal processing circuits, motor drive circuits, lighting and control systems. It is also applicable for powering “smart” and “intelligent” digital systems, such as those used in automation, measurement, sensor, and electronic security solutions.

Working Principle

The REC5-4809SRWZ/H4/C/SMD-R is a buck-boost converter, which operates on the basic concepts of energy conversion and power transfer. The converter is connected to both the input and output power sources and converts the input DC voltage to the desired output DC voltage.

To do so, the converter has two energy storage components; an inductor and a capacitor. The inductor stores electrical energy in the form of a magnetic field and the capacitor stores electrical energy in the form of an electric field. Whenever a voltage change occurs across the inductor, it releases the stored magnetic energy as a current which is used to charge the capacitor.

The capacitors in turn, releases the stored electric energy to the load, providing the desired output voltage. The converter also includes an internal control circuit which monitors the output voltage and adjusts the energy transfer process accordingly to maintain the output voltage at the desired level.

Conclusion

The REC5-4809SRWZ/H4/C/SMD-R is a DC/DC converter used in a variety of applications. It is used for powering signal processing circuits, motor drive circuits, lighting and control systems, as well as powering smart digital systems. The converter works through the transfer of energy from the inductor and capacitor, the input to output voltage is adjusted via an internal control circuit.
