DC/DC converters provide power conversion mechanisms between two voltage sources, allowing for the efficient power supply of circuits for various applications, ranging from basic security modules to advanced mechatronics systems. In the specific case of RW2-1215S/SMD DC/DC converters, these serve as permanent magnet step-down converters with specific characteristics suited for specific applications.

Below is a description of the application field and working principle of RW2-1215S/SMD DC/DC converters.

Application Field

RW2-1215S/SMD DC/DC converters are specifically designed to be used in voltage-controlled inductive loads, such as in LED lighting and charging systems. These converters feature several advantages, such as: wide temperature range, high efficiency, and low heat generation.

In the case of LED lighting, the wide temperature range of RW2-1215S/SMD DC/DC converters makes them especially suitable for a variety of indoor and outdoor lighting applications, due to the ability to provide stable operation even in extreme temperatures. This makes them particularly suitable for lighting in public areas. The high efficiency of the converters prevents energy wastage, while the low heat generation keeps light fixtures cool and provides additional efficiency.

In the case of charging systems, RW2-1215S/SMD DC/DC converters are suitable for both high and low voltage components, such as those found in automotive systems. The wide operating temperature range and the low heat generation results in stable operation over many years of use. The high efficiency of the converters ensures that little energy is wasted, making them an ideal choice for automotive charging systems.

Working Principle

The RW2-1215S/SMD DC/DC converters are permanent magnet step-down converters with high efficiency and low noise levels. These types of converters work by converting an input voltage to an output voltage that is lower than the input voltage. This is done by using a DC/DC converter circuit, which consists of an inductor, a rectifier, a capacitor, and a transistor.

The inductor and the rectifier make up the main power converting components. The inductor stores energy when a current passes through it, and the rectifier converts the alternating current into a direct current. The transistor helps regulate the current flowing through the converter, and the capacitor acts as a buffer, helping to maintain the output voltage.

The mechanism of how a permanent magnet step-down converter works is relatively simple: The magnetised core stores energy when the current passes through it, while the rectifier and transistor regulate the current and maintain the output voltage. When the current enters the converter, it passes through the inductor, and is then regulated by the transistor.

The result of this conversion and regulation is a lower output voltage than the input voltage. This makes RW2-1215S/SMD DC/DC converters especially efficient and suitable for use in voltage-controlled inductive loads such as LED lighting and charging systems.
