Introduction

DC DC Converters are used to produce electrical power from a direct current (DC) source. They convert DC power to a different voltage or current level and are used extensively in vehicles, industrial and consumer electronics, and telecom and data communications equipment. REC5-483.3SRW/H6/A/SMD/CTRL-R is a popular DC DC converter with a wide range of applications.

REC5-483.3SRW/H6/A/SMD/CTRL-R Overview

The REC5-483.3SRW/H6/A/SMD/CTRL-R offers a high efficiency of 95%, an input voltage range of 5.5V to 48V and is capable of providing a maximum output current of 1.5A. It has a small footprint, making it ideal for use in limited space applications, and also offers an optional wide input voltage range of 5.5V to 58V. The device is also protected against over-voltage and over-temperature, and offers built-in EMI suppression, making it suitable for applications such as automotive, telecom, data communications, industrial and consumer electronics.

Application Field and Working Principle

The REC5-483.3SRW/H6/A/SMD/CTRL-R is widely used in various applications including automotive electronics, telecom and data communications, industrial and consumer electronics. The device is designed to provide highly regulated output voltages of up to 5.6V (at 1.5A). It can be used to convert 5.5V to 48V input supply to 5.6V output with a high efficiency of up 95%.The device utilizes a switching-regulator (SR) operating principle. The SR uses a smaller chip for the power conversion, which is more efficient and has higher power density compared to linear regulators. As the SR is switching at a high frequency, a low-pass filter is needed to filter out the high-frequency noise from the output. The RC5-483.3SRW/H6/A/SMD/CTRL-R also offers built-in EMI suppression, providing low EMI emissions. The SR works by chopping the input DC into a square wave, whereby the input voltage is switched between 0V and high voltage by a semiconductor switch. The output voltage is then adjusted (controlled) by varying the duty cycle of the square wave. This duty cycle can be varied by a control circuit, allowing the output voltage to be regulated. The REC5-483.3SRW/H6/A/SMD/CTRL-R is protected against over-voltage and over-temperature and also offers overload protection.

Conclusion

The REC5-483.3SRW/H6/A/SMD/CTRL-R is a popular DC DC converter with a wide range of applications in automotive electronics, telecom and data communications, industrial and consumer electronics. The device utilizes a switching-regulatorSR operating principle and offers high efficiency, wide input-voltage range, low EMI emissions, over-voltage and over-temperature protection and overload protection, making it suitable for a variety of applications.
