DC-DC Coeverters

DC-DC converters are electrical and electronic components which convert direct current from one voltage level to another. By providing isolation between the input and output circuits, and by providing conversion from AC to DC or vice versa, they are an important component of modern electrical systems. The REC5-4805SRWZ/H2/A/SMD/CTRL-R is a specific type of DC-DC converter manufactured by Delta Electronics, Inc.

Application field

The REC5-4805SRWZ/H2/A/SMD/CTRL-R is a high-efficiency, regulated DC-DC converter. It has been designed for use in a variety of high-power applications, including point-of-load (PoL) supplies, telecom power supplies, and industrial power supplies. It is also suitable for use in medical equipment and shallow depth applications, as it is lightweight and space effective.

Working principle

The REC5-4805SRWZ/H2/A/SMD/CTRL-R works on the principle of an active clamp synchronous rectification topology, in which a power transfer is achieved through a combination of synchronous rectification and control circuitry. It is designed to provide a high level of efficiency, with low output ripple and fast transient response for transient load events.

The converter utilizes advanced MOSFET devices for synchronous rectification, providing high operating efficiency and low gate drive power consumption. A full range of control features, including easy start-up, adjustable-soft-start/stop, adjustable zero-current switching and frequency dithering are also included in the design. The converter is protected against a range of conditions, such as over-temperature, over-voltage and over-current.

Conclusion

The REC5-4805SRWZ/H2/A/SMD/CTRL-R is a high-efficiency, regulated DC-DC converter designed for use in a wide range of applications. It utilizes an active clamp synchronous rectification topology, providing high efficiency and low output ripple, while offering comprehensive control features to ensure safe and efficient operation.
