DC DC converters are an important part of many electric circuits and provide efficient power conversion between AC and DC. The R0.25S-0512-R DC-DC Converter is one of the latest additions to the large family of voltage conversion solutions. This converter utilises synchronous rectification to provide high efficiency in a wide range of applications.

Features

The R0.25S-0512-R is a step-down DC-DC converter with a wide input voltage range of 5.5 VDC to 72 VDC. It also features an adjustable output voltage range between 0.5 V to 12 V. Its output current can reach up to 25 A, and it is designed to provide several levels of protection against over voltage, over current and short circuit conditions. It is also able to implement a low standby power loss of 40 mW at 12 V with its integrated power down feature. This DC-DC converter is a compact solution that occupies only 5 cm2 in a typical application.

Application Field

The R0.25S-0512-R is well suited to a wide range of industrial applications, including automation, automotive, and communications. Its wide input voltage provides the flexibility to be powered from various sources, such as 12, 24, or 48 VDC batteries and adapters. This is especially useful for applications where the input voltage is not fixed, such as on-field power supply. The device is also highly efficient with its synchronous rectification feature, which allows it to provide 95 % efficiency for load currents ranging from 2 A to 25 A. The device also has an embedded battery support voltage feature, which allows it to support a variety of battery chemistries.

Working Principle

The R0.25S-0512-R is a synchronous buck converter. This type of converter works by using an inductor to perform energy transfer between the input and the output. When the switch is on, energy is transferred from the input to the output, then the switch is off, the inductor stores energy in its magnetic field. The output voltage is then adjusted by varying the duty cycle (Pulse Width Modulation) of the switch. The converter also uses synchronous rectification at the output stage, which improves efficiency by cutting the power losses in the output stage (Diode stored energy).

Conclusion

The R0.25S-0512-R DC-DC converter is a high-performance solution for applications requiring wide input and output voltage ranges. With its maximum output current of 25A, it is able to handle the power requirements of many industrial applications. Its integrated synchronous rectification technology provides high efficiency as well as low standby power losses. The R0.25S-0512-R is a cost-effective solution for applications requiring advanced performance and efficiency.
