DC-DC converters, or direct current-direct current converters, are energy conversion devices that are used to convert DC voltage from one level to another. REC5-4809DRW/H/B/SMD-R is a general purpose, high-efficiency, wide input voltage DC-DC converter. It is an ideal solution for a wide range of applications.

Applications

The REC5-4809DRW/H/B/SMD-R converter is typically used in applications that require DC output and where the output needs to be regulated. This makes the converter ideal for applications such as server power supplies, communications equipment power supplies, instrumentation/measurement systems, and industrial control systems. It is also a great solution for medical equipment, renewable energy systems, and battery-powered devices that require extremely reliable and efficient converters.

Features

The REC5-4809DRW/H/B/SMD-R converter features a wide input voltage range of 6 to 24 Volts, a wide output voltage range up to 48 Volts, and an output power rating of up to 40 Watts. It also provides high efficiency of up to 98% and a fast transient response time. The converter can also be configured to meet special requirements such as wide temperature ranges, efficiency curves, and adjustments for specific applications.

The converter is also designed with integrated EMI/RFI filtering, enabling it to meet or surpass current EMC/EMI standards. It also includes an onboard thermal protection feature that shuts off the converter when the temperature rises above the set threshold. This helps protect the components from being damaged in the event of overheating.

Working principle

The REC5-4809DRW/H/B/SMD-R converter operates on the principle of pulse-width modulation. This is a method of controlling the output voltage through rapid switching of the power transistors. The converter monitors the output voltage and adjusts the duty cycle of the power transistors accordingly. The result is an output voltage that is stable and regulated.

In addition, the converter utilizes a feedback control loop to ensure maximum accuracy of the output voltage. This feedback loop includes an Error amplifier, a Comparator, and a Driver circuit. The Error amplifier compares the output voltage with a Voltage Reference and produces an error signal. The Comparator circuit then compares the error signal to the ramp signal generated by the internal oscillator. Finally, the Driver translates the error signal into a PWM signal, which is used to control the switching of the power transistors.

Conclusion

The REC5-4809DRW/H/B/SMD-R converter is an ideal solution for a wide range of applications requiring DC output and reliable voltage regulation. It features a wide input voltage range, a wide output voltage range, high efficiency, fast transient response time, and onboard EMI/RFI filtering. The converter utilizes pulse-width modulation and a feedback control loop to ensure accurate voltage regulation. Thus, the REC5-4809DRW/H/B/SMD-R is an ideal DC-DC converter for a variety of applications.
