DC DC Converters – REC5-1212SRW/H2/C Application Field and Working Principle

DC-DC converters are designed to take an unregulated direct current voltage from an alternative power source, such as a battery or solar panel, and transform it into a regulated direct current voltage necessary to power a device. DC-DC converters are used in various application fields, ranging from electrical engineering and automotive to consumer electronics. The REC5-1212SRW/H2/C is a medium-powered DC-DC converter designed to convert an unregulated input voltage ranging from 5V to 19V DC into a regulated 12V output, with a maximum power rating of 17W. The converter is designed for use in applications such as low voltage lighting systems, peripheral devices, and safety systems.The REC5-1212SRW/H2/C uses an efficient flyback topology for its power conversion process. The flyback topology uses a single switch, in this case a transistor, and a single inductor, as well as several capacitors and built-in protection circuits, in order to perform the power conversion.The working principle of the REC5-1212SRW/H2/C is as follows. When the switch is off, energy stored in the inductor is transferred to the output capacitors, which provide the continuous supply of current in order to power the load. The output capacitors also help to smooth out any ripple present in the rectified input voltage, while the inductor helps to prevent overshoot and undershoot.When the switch is temporarily closed, energy from the input is transferred to the secondary winding of the transformer in order to generate the regulated output voltage. The current flowing in the primary side of the transformer magnetizes the core. When the switch is opened, the energy stored in the magnetic core is released and the energy is transferred to the output capacitors.This cycle continues in order to maintain a constant output voltage in the presence of varying input voltage. The inductor helps to limit current spikes while the built-in protection circuits help to protect the converter from over current, over voltage, and over temperature conditions.The REC5-1212SRW/H2/C is a versatile, medium power DC-DC converter for applications requiring a regulated voltage output in the presence of varying input. The efficient flyback topology and built-in protection circuits make the converter well-suited for a wide variety of applications, ranging from low voltage lighting systems to peripheral devices and safety systems.
