DC-DC converters are vital components in the world of energy management and power electronics, and the REC3.5-2415DRW/R8/A converter is an example of how these components can have a big impact in many industrial, commercial, and residential applications. In this article, we will discuss the application field and working principle of this particular device.

Application Field

The REC3.5-2415DRW/R8/A is a DC-DC converter typically used in applications where a stable second voltage is needed, such as with DC/DC boosting for batteries, AC/DC buck-boost converters, and isolated power supplies. This converter can take an input of 3.5V DC, and output either 3.3V or 5V DC. It is a reliably efficient device, with a total power conversion rating of 15 Watts. The device is quite compact, only taking up 0.9 inches by 0.6 inches of space, and also very lightweight, weighing in at just 6.3 grams. Due to its size and performance characteristics, it is often used in applications where a more substantial and space-intrusive solution can’t fit, such as those found in medical, test & measurement, and communications equipment.

Working Principle

The device works by taking in the input voltage and boosting it up, while simultaneously also creating a stable output voltage. This is achieved using a variety of components, which then work in harmony to create the desired output parameters. The internal workings can be broken down into two components: control circuitry, and power components. The control circuitry, which is done via a four-pin PWM system, is responsible for regulating the power signals in order to yield the required output voltage. The power components, meanwhile, are responsible for taking the input and outputting the required voltage. These components include a step-up transformer, inductor, and a MOSFET (metal-oxide field effect transistor) switch.

The step-up transformer steps up the incoming 3.5V DC into a much higher voltage which is then supplied to the inductor. The inductor acts as an energy storage and slows down the rate of change of current in order to stablise the voltage. This energy is then transferred to the second output side of the converter via the MOSFET switch. This switch acts like a valve and is opened and closed by the control circuitry in order to regulate the output voltage. Finally, the output voltage is then stabilised by a small-size, high-efficiency filter inside the converter.

Conclusion

The REC3.5-2415DRW/R8/A is an ideal DC-DC converter for applications that require a second, stable voltage output from a 3.5V input. This device typically finds use in medical, communications, test & measurement, and many other industries due to its size, power rating, and efficiency. The device uses a step-up transformer, inductor, and MOSFET switch in order to convert the input into the desired output voltage, with control circuitry regulating this whole process. For small, compact, and powerful DC-DC conversion, the REC3.5-2415DRW/R8/A is a great choice.
