DC-DC converters are electrical components used to convert one type of DC voltage to another lower or higher voltage. There are a variety of DC-DC converters available in the market, and a popular choice is the REC5-4805SRWZ/H6/C/SMD-R.

Overview of the REC5-4805SRWZ/H6/C/SMD-R

The REC5-4805SRWZ/H6/C/SMD-R is a non-isolated buck/boost DC-DC converter with a 5V to 40V input voltage range and a 0.6V to 5V output voltage range. It is a step-down/step-up converter, providing continuous current up to 5A with ± 2% accuracy and an efficiency up to 96%. The unit is packaged in a 8-pin surface-mount (SMD) casing, and is approved by the UL 60950-1 safety standard. It offers excellent EMI, ESD, and OVP features, and has a wide ambient temperature range of -40℃ to +125℃.

Application Field

The REC5-4805SRWZ/H6/C/SMD-R is suitable for a variety of applications, most notably in those requiring high input and output voltage accuracy, as well as high step-down or step-up capability. It is commonly used in a wide range of non-isolated buck/boost circuits, as well as in automotive, industrial, and consumer electronics. It is also used in battery-powered applications, including mobiles, laptops, and telecom devices.

Working Principle

The REC5-4805SRWZ/H6/C/SMD-R works on the basic principle of buck/boost regulation. By varying the duty cycle of an H-bridge circuit, it effectively reduces or increases an input DC voltage to the desired output voltage. It works by first conditioning the input voltage to maintain an output voltage accuracy of ± 2%, and then cutting off the voltage at a specified state before entering a stand-by mode.

The REC5-4805SRWZ/H6/C/SMD-R is equipped with a number of protection features, such as a low-current trimming circuit which reduces the continuous current to 0.7A if the output voltage is below 0.7V, and an overvoltage protection feature to prevent excessive output voltage. Additionally, it is equipped with a thermal protection function to reduce the input current in case of a power surge or overload.

Conclusion

The REC5-4805SRWZ/H6/C/SMD-R is a versatile and reliable DC-DC converter that is capable of providing continuous current of up to 5A and a high output voltage accuracy of ±2%. With its wide input and output voltage ranges, it is suitable for a variety of applications, including non-isolated buck/boost circuits, automotive, industrial, and consumer electronics. Additionally, it has a number of protection features to ensure safe operation in a variety of environments.
