DC DC Converters

DC-DC converters are electronic circuits that use the electric energy of a DC power source to convert it into another form of energy such as AC, DC, or a combination of AC and DC, that can be used for various purposes. DC-DC converters are used for a variety of applications, such as power supply applications, UPS systems, lighting systems, instrumentation, and many more.

R2D-0524 Application Field and Working Principle

The R2D-0524 DC-DC power module is a widely used medium power DC-DC converter designed for use in a wide range of industrial, automotive, telecommunications, electrical, and consumer applications. It is also used in test and measurement systems. The R2D-0524 can provide up to 24VDC output voltage from a rectified DC input voltage ranging from 9VDC to 28VDC. It can provide an output current of 5A with a maximum efficiency of 94%.

The R2D-0524 working principle is simple. It uses a two-stage topology including an input and output stage. The input stage is made up of an electrolytic capacitor, a voltage regulator, and a filtering coil. A diode rectifier bridge is placed in series with the input voltage and is used to drop the input voltage to the regulation level. The voltage regulator takes the incoming DC voltage and regulates it to the output voltage. The output stage consists of two separate output converters, an LDO voltage regulator and an active Quasi-Resonant (QR) converter. The QR converter works in a continuous conduction mode and has a unique control structure, providing ultra-low ripple, high efficiency, and wide output voltage programming range.

The R2D-0524 also has a number of protection features to protect the system from over-voltage, over-temperature, short circuits, and overloads. As an added safety feature, the unit is qualified to the R2D-0524 safety standards. This includes 60-second short circuit protection, and one-minute complete output shut down. It also has a built-in reset function for recovery from an over-temperature condition.

The R2D-0524 is a widely used power component with a high efficiency, low cost, and low EMI features. It is ideal for a wide variety of applications requiring high efficiency, high capacity power conversion.
