DC-DC converters are widely used in a variety of applications. REC3-4809SRWZ/H4/C/SMD-R is a DC/DC converter specifically designed for powering high-performance system applications. This article will discuss the application fields and working principle of this DC/DC converter.

The REC3-4809SRWZ/H4/C/SMD-R is a 1500 Watt DC/DC converter designed for isolated DC/DC conversion. It uses synchronous rectification for high efficiency, very low EMI, and excellent dynamic load response. This DC/DC converter is available in a wide variety of package configurations, including a 1U 19” rack-mountable form factor, making it well suited for space constrained applications. The REC3-4809SRWZ/H4/C/SMD-R is ideal for applications that require high power with low noise, such as industrial automation, telecom, medical, military, and aerospace.

The REC3-4809SRWZ/H4/C/SMD-R features an innovative design, incorporating a wide range of protection functions to ensure a robust operation. The device is designed with short circuit protection, current limiting protection, over-temperature protection, over-voltage protection, and current-mode control. Additionally, the REC3-4809SRWZ/H4/C/SMD-R offers a unique function called “Auto-Restart” – an algorithm which gives the device the ability to automatically restart after a short circuit or over-temperature event.

The REC3-4809SRWZ/H4/C/SMD-R utilizes a unique switching architecture to ensure a highly reliable operation and excellent dynamic load response. It consists of two independent switching stages: a high-frequency zero voltage switching (ZVS) stage and a low-frequency output stage. The ZVS stage is responsible for power density and efficiency, while the output stage is responsible for the output voltage ripple and noise. Both stages are designed to work together to ensure that the device meets the highest standards of performance.

In addition to its versatile features, the REC3-4809SRWZ/H4/C/SMD-R provides a broad input voltage range from 18V to 75V. It is also equipped with a built-in adjustable switching frequency, allowing users to adjust the frequency for better EMI management or to optimize efficiency. The device also includes an on/off control pin that can be used to shut down the converter when it is not in use.

The REC3-4809SRWZ/H4/C/SMD-R provides excellent performance in a variety of challenging environments. It is designed to operate at full load in temperatures from -40°C to +120°C and provides a low output noise of only 0.5mVrms. The device is designed with additional safety features including soft-start, under-voltage lock-out, over-voltage protection, and over-current protection.

The REC3-4809SRWZ/H4/C/SMD-R is ideal for applications that require high power with low noise, such as industrial automation, telecom, medical, military, and aerospace applications. With its innovative design, robust protection functions, and high-performance features, the REC3-4809SRWZ/H4/C/SMD-R is an excellent choice for powering mission critical systems in challenging environments.
