DC-DC converters are voltage regulators that change existing DC voltage into another voltage level. REC3-4805SRW/H/B/SMD-R is one of these converters and has a wide range of applications and working principles.

Application Field

REC3-4805SRW/H/B/SMD-R DC-DC converters are commonly used in a variety of industries, such as telecoms, automotive, medical, and military. It is suitable for both industrial and consumer applications. For example, it can be used in electric vehicles to convert the battery voltage to the necessary voltage for power accessories. It is also used in medical device to provide voltage adjustments for X-Ray machines or MRI scanners. Additionally, it can be used in radio and telecoms equipment where multiple voltages are needed.

Working Principle

DC-DC converters are designed to take input voltage from a fixed source, such as a battery source or the output of an AC-DC rectifier, and convert that voltage into a different, adjustable output voltage. REC3-4805SRW/H/B/SMD-R DC-DC converters use pulse width modulation (PWM) to control the output voltage.

The PWM signal is generated by a control IC, which contains functions such as current regulation, overvoltage protection, and temperature protection. The PWM signal is passed through a transformer, which amplifies the signal and passes it to the rectifier and filter circuit. The output voltage is then determined by the voltage and current characteristics of the transformer, the rectifier, and the filter.

REC3-4805SRW/H/B/SMD-R DC-DC converters are highly efficient and can be used in a wide variety of applications, due to its adjustable output voltage, high efficiency, and temperature protection features. Moreover, its overall small size makes it very convenient for embedded applications.
