DC DC Converters - RSS-0509-R Application Field and Working Principle

DC-DC converters are widely used in different electronic applications and have become an important part of the modern electrical power system. The RSS-0509-R DC-DC Converter is one such example of a very popular and reliable converter. It is an isolated DC-DC converter that provides reliable and efficient power conversion in a variety of industrial and commercial applications.

Overview of the RSS-0509-R DC-DC Converter

The RSS-0509-R is a semi-module DC-DC converter with a maximum output power of 9W. It is designed with constant voltage or current outputs, and features a wide input voltage range from 9VDC to 24VDC. The output voltage of the device is adjustable from 0.9VDC to 5.4VDC, with a typical conversion efficiency of up to 91%. The minimum start-up voltage is 3V.

The RSS-0509-R is equipped with a unique, high input/output impedance feature that prevents the output voltage from overshooting or tipping-over. It has internal surface mountable components for improved design integrity and durability. The double regulation scheme also ensures sub-millisecond transient response time, and excellent line/load regulation ability that make it highly suitable for medical equipment, motor drives, and other sensitive applications.

Application Field of the RSS-0509-R DC-DC Converter

The RSS-0509-R is designed to provide reliable, high-efficiency power conversion in industrial and commercial applications. It is ideally suited for use in medical equipment, motor drives, and sensitive industrial/commercial power systems, due to its excellent line/load regulation abilities, fast transient response time, and tight output voltage and current specifications.

The RSS-0509-R is also designed to provide a nominal input voltage of 24V. It is suitable for supplying low-power voltage rail requirements in a variety of industrial, medical, and commercial electronic systems, such as computers, telecommunication systems, ATM machines, and point of sale equipment. The device can also be used to provide power to lighting equipment, position/photo detectors, printers, and other peripheral devices.

Working Principle of the RSS-0509-R DC-DC Converter

The RSS-0509-R DC-DC converter uses a unique, adaptive, full-wave rectifier technology to achieve a high level of efficiency as well as excellent input/output regulation accuracy. It utilizes a DC-to-DC conversion principle, known as interleaving, to reduce the total output ripple and noise.

The device operates in a closed-loop regulation scheme, where the output voltage is monitored and feedback to the control electronics, which adjusts the input voltage accordingly. The device requires minimum input voltage to start and can draw up to a maximum input voltage, as the output voltage increases or decreases, the input voltage is adjusted accordingly.

In addition, the RSS-0509-R also utilizes a unique, buck-type topology that allows for efficient power transfer, while still providing high dynamic response and very low output impedance. This also allows for excellent power transfer efficiency, as well as very low noise and vibration.
