DC-DC converters transform one DC voltage to another, typically with higher or lower voltage, while maintaining the same current. The REC3-4809SRWZ/H2/C/SMD is a DC-DC converter widely used in a variety of applications including industrial, automotive, medical, and consumer electronics. This converter offers a wide input range from 4.5V - 9V, making it suitable for a wide range of input sources.

The device features an integrated flyback transformer for excellent power efficiency and a high switching frequency of up to 450 kHz. The integrated transformer also offers improved EMI performance and reduced radiated emissions. The active filtering and switching technology eliminates the need for an external output filter, saving space and cost. It also provides lower output ripple and noise than standard flyback converters. The device is designed for natural convection cooling with no need for a heatsink or fan.

The REC3-4809SRWZ/H2/C/SMD has a wide set of features, including an on/off indicator, overcurrent protection, overtemperature protection, output overload protection and overvoltage protection. The high operating temperature range of -40°C to +85°C means there is no need to derate the output power even in extreme temperatures, making it suitable for use in harsh environments. The multiple safety protections make the device highly reliable and suitable for critical applications.

In terms of performance, the REC3-4809SRWZ/H2/C/SMD DC-DC converter can provide 95% power efficiency and an output current up to 3.6A. The 91% peak efficiency ensures minimal power loss and power dissipation. The device also features an integrated soft start function that reduces inrush current and output voltage overshoot.

The REC3-4809SRWZ/H2/C/SMD has a number of applications including industrial equipment, telecommunications, automotive electronics, servers, and medical electronics. It is particularly well-suited for applications requiring a robust and reliable power supply. The high power efficiency and integrated safety functions make this converter an excellent choice for applications where power consumption and cost efficiency are critical.

The REC3-4809SRWZ/H2/C/SMD works by rectifying the incoming AC voltage to DC voltage, which is then converted to the requested output voltage by the switching regulator. The switching regulator consists of two main components – an inductor and a switch which are driven by a PWM signal. The inductor stores energy for a short period of time, while the switch is used to release that energy, which eventually reaches the output. This process is repeated on and off at a high frequency. The converter provides a constant output voltage, even with changes in input voltage or load. This makes it ideal for applications where the output voltage needs to remain stable.

The REC3-4809SRWZ/H2/C/SMD DC-DC converter is an excellent choice for applications requiring a cost-effective, reliable power supply. Its wide input range, high power efficiency, and integrated safety functions make it well-suited for a range of industrial, automotive, medical, and consumer electronics applications.
