Introduction to DC DC Converters

DC-DC converters are electrical devices that are used to convert a source of direct current (DC) into another form of DC. They can be used to provide a higher voltage, a lower voltage, or even AC power from DC sources. DC-DC converters are essential elements of many electrical systems, providing power from a variety of sources.Typically, DC-DC converters are found in computers, laptops, spacecraft, solar cells, and various other electronic devices. Essentially, they allow energy to be converted from one form to another, and can be used to increase the efficiency of power distribution systems.

REC3-4805DRW/H6/A/SMD/CTRL-R application field and working principle

The REC3-4805DRW/H6/A/SMD/CTRL-R is a DC-DC converter made by RECOM that is designed specifically for applications that require a high power density. It operates from a wide 4:1 input voltage range of 12-48V, and can deliver an output of 0 – 55V/100A. Additionally, the device features a high efficiency up to 95%, and a low no-load power consumption of less than 50mA.The REC3-4805DRW/H6/A/SMD/CTRL-R utilizes a pulse width modulated (PWM) control topology with a digital controller, allowing it to achieve low cost and excellent regulation accuracy. The device is also equipped with a range of advanced protection features, including output voltage programming, over-voltage protection (OVP), current limit protection (CLP), and over temperature protection.The REC3-4805DRW/H6/A/SMD/CTRL-R has wide application field, especially in industrial and telecom applications. It can be used to supply additional power to machines, such as in portable drill and saws, and also for various types of industrial electronic equipment, such as 3D printers, robots, and sensors. Furthermore, telecommunications equipment requiring higher voltage can also benefit from this device.The working principle of the device is based on a PWM control loop which helps to regulate the output voltage. When a load is connected, the high-side PMOS transistor is turned on, while the low-side NMOS transistor is turned off. This creates a voltage drop at the rectifier, causing current to flow from the input to the output. The output voltage is then regulated by the on/off cycle of the PMOS and NMOS transistors.

Conclusion

The REC3-4805DRW/H6/A/SMD/CTRL-R DC-DC converter is an excellent device for applications requiring a high power density. It is equipped with advanced protection features and utilizes a PWM control topology, allowing it to achieve high efficiency and excellent regulation accuracy. With its wide input voltage range and high current delivery, it can be used in a wide range of industrial and telecom applications.
