DC DC Converters are electronic devices that can convert Direct Current (DC) from one voltage to another voltage. REC3-4815DRWZ/H/B/M/SMD is among such devices that are used in a variety of applications for its power efficiency and reliability. This article looks into the application fields, working principles and other aspects of REC3-4815DRWZ/H/B/M/SMD.

Application Field

REC3-4815DRWZ/H/B/M/SMD is a single-output, surface mount, and non-isolated DC/DC converter. It has an output range of up to 48V with an input voltage range of 4.5V to 15V, which makes it suitable for a broad range of applications such as automotive, industrial, telecom, medical, consumer, computing, and more. The flexible input voltage range enables different applications such as solenoid/valve drivers, PLC’s motors, and sensors that require different voltages.

The REC3-4815DRWZ/H/B/M/SMD features high efficiency of up to 90%, no-load power consumption of only 10mW, current limit protection as standard, fanless operation up to 65°C, and a high power density of 3.3W/cm3. The device also offers an over-temperature protection (OTP), enabling the device to protect itself from over-current faults, short circuits, and other malignant faults.

The REC3-4815DRWZ/H/B/M/SMD is designed with wide input voltage range, high current, and low output ripple, and its high efficiency and reliability makes it the ideal choice for applications that require continuous power and operate in severe environments.

Working Principle

The working principle of REC3-4815DRWZ/H/B/M/SMD can be understood as a combination of two regulators, one buck regulator for the main output and an over-current protection (OCP) circuit for OCP and over-temperature protection (OTP). The buck regulator consists of a power switch and an inductor, with a voltage reference circuit setting the output voltage. The OCP circuit has a comparator and a sense transformer that monitors the output current and compares it to a threshold.

When the output current exceeds the threshold, the OCP circuit will shut off the switch and will reset the start up sequence once the output current falls below the threshold. The OCP therefore provides over-current protection, as well as over-temperature protection. The OTP circuit is triggered when the temperature of the device exceeds a certain threshold.

Advantages

The advantages of REC3-4815DRWZ/H/B/M/SMD are its high efficiency, small size, wide input voltage range, high current rating, and low ripple. Additionally, the unit is designed for fanless operation up to 65°C, making it suitable for tough environments. The REC3-4815DRWZ/H/B/M/SMD also offers OCP and OTP protection, which is critical for safety and reliability.

Conclusion

In conclusion, the REC3-4815DRWZ/H/B/M/SMD is a reliable and efficient DC/DC converter that fits a variety of applications. The device provides high current and efficiency, small size, flexible input voltage range, and advanced protection that makes it suitable for hazardous environments. It is definitely a good solution for applications that require continuous power.
