DC DC Converters

DC DC Converters are electrical components which enable power conversion from one DC voltage level to another DC voltage level. The specific component REC5-4805DRWZ/H/B/SMD is a Step-Down DC to DC Converter for use in a variety of power conversion applications.

General Description

REC5-4805DRWZ/H/B/SMD is a DC to DC converter with high efficiency and excellent transient responses suitable for point-of-load applications with multiple outputs. It is designed for a wide input voltage range from 4.5 V to 18 V and can deliver 600mA of continuous current at the output, with a maximum peak current of up to 1 A. The device includes a wide array of features and protections such as over-voltage protection, over-current protection and thermal shutdown.

Application Field

Notably, the REC5-4805DRWZ/H/B/SMD is used in numerous different power conversion applications, including telecommunication systems, industrial systems, motor drivers, automotive electronics, computers, audio amplifiers, battery-powered systems, and many other power systems. Its features, such as its wide voltage range and various protections, make it an ideal choice for these applications.

Working Principle

The REC5-4805DRWZ/H/B/SMD utilizes a Buck topology combining an integrated high-side FET switch and a low-side FET diode to achieve step-down conversion of input voltage to output voltage. This circuit consists of an inductor, a capacitor, two input ports, and two output ports. When the FET is high, energy is stored in the inductor. When the FET is low, energy is stored in the capacitor. Therefore, this circuit enables energy conversion from one DC voltage to another.

Susceptibility and Shielding

The REC5-4805DRWZ/H/B/SMD product does not require an external Voltage Regulator due to its integrated power conversion outputs, thus it is more reliable and has a longer lifespan than components with external Voltage Regulators. Additionally, it has a wide input range, which allows it to reduce the amount of parts and components required for power conversion without affecting the performance of the component. Being a DC to DC converter that is used in various power systems, it is susceptible to noise interference from external environments. The device is designed to be resistant to interference by external sources such as EMI, ESD, and EFT noise, but proper shielding is essential to ensure that it operates properly. A common solution for this is to use microwave absorbing materials in the design to reduce the amplitude of noise on the components and maintain the device\'s performance.

Conclusion

The REC5-4805DRWZ/H/B/SMD is a highly efficient DC to DC converter for wide input range point-of-load applications with multiple outputs. Its use is mainly in telecommunication systems, industrial systems, motor drivers, automotive electronics, computers, audio amplifiers, and battery-powered systems, as it is designed to deliver 600mA of continuous current at the output with a peak current of up to 1A and offers various protectional features. However, to ensure its performance, its susceptible to outside noise interference and proper shielding should be applied.
