DC DC Converters: RW2-4805D/B Application Field and Working Principle

DC/DC converters are used in many applications from portable electronics to large-scale industrial equipment. The RW2-4805D/B is a 5V/12V inrush current limit 2A DC-DC converter module from MICropower Direct that was designed for use in applications that require high power, safety, and reliability.

Applications:

This particular converter can be used in a variety of applications including inverters, battery management systems, automotive electronics, power supplies, mining, and robotics. It is also used in medical device applications, where it is used to provide power to sensitive equipment. The module can handle input voltages from 5-30 volts with an adjustable output voltage up to 14V. It is capable of providing up to 2A of current continuously. The module also features an inrush current limit of up to 10A, which helps to maintain power efficiency during times of peak load.

Design:

The RW2-4805D/B is a surface mount device with a footprint of only 2.8 x 1.4mm. It features an internal integrated circuit with a low-noise electromagnetic interference (EMI) filter. It also has an additional capacitor for energy storage. The converter is made using high-quality materials, allowing it to operate efficiently in extreme temperatures ranging from -40°C to 105°C.

Working Principle:

The converter works based on the buck converter topology, which uses an inductor, a diode, and a capacitor to step down voltage. When voltage is applied, the inductor stores energy and then releases it to the output when the switch turns off. This results in a decrease in output voltage, which is then regulated by an internal linear regulator. The input side of the module is protected with an overtemperature thermal shutdown, while the output side has surge protection.

Conclusion:

The RW2-4805D/B is a high-performance 5V/12V inrush current limit 2A DC-DC converter module. It can handle input voltages ranging from 5-30 volts and provides an adjustable output voltage up to 14V. Its small footprint and reliable performance make it suitable for many applications, from medical devices to robotics. It works using a buck converter topology, which uses an inductor, a diode, and a capacitor to step down voltage. The module is protected with an overtemperature thermal shutdown and surge protection.
