DC-DC converters are important electronic components of electronic circuits and systems. REC3-4809DRW/H4/A/SMD is one of them, providing low-voltage power sources suitable for a variety of applications including telecommunications, automotive, navigation, and energy monitoring. As its name implies, REC3-4809DRW/H4/A/SMD is an off-line, dual-channel device that can provide both high-voltage and low-voltage power sources with a single input voltage of nominally 48 volts. The REC3-4809DRW/H4/A/SMD DC-DC converter consists of an isolated dual output diode rectifier, a polarized electrolytic capacitor, an inductor, a transformer, and two Ultra-Low-Voltage (ULV) MOSFETs.

The working principle of the REC3-4809DRW/H4/A/SMD DC-DC converter is based on its off-line, dual-channel design. In this design, two separate and distinct channels each step-down a 48-volt input voltage to two isolated output voltages. The REC3-4809DRW/H4/A/SMD then feeds the two output voltages to its respective isolated diode rectifiers. The diode rectifiers output beats are then passed through the device’s inductor and capacitor components, which act as filter elements to provide a clean and ripple-free output. The inductor and capacitor are then connected to the transformer, which further reduces the output voltage to the desired output voltage.

The Ultra-Low-Voltage (ULV) MOSFETs are the driving force behind the REC3-4809DRW/H4/A/SMD DC-DC converter. The MOSFETs control the flow of current to the output stage. As the output load increases, the MOSFETs reduce the output voltage, and as the load decreases, the MOSFETs increase the output voltage. This process of current regulation is known as Pulse Width Modulation (PWM).

The REC3-4809DRW/H4/A/SMD DC-DC converter has a variety of application fields, such as communications, automotive, navigation, energy monitoring, and storage. Communications applications require voltage levels compatible with most electronic components, as well as efficient current regulation. The REC3-4809DRW/H4/A/SMD provides efficient current control and does not require extensive and expensive heat sinks and cooling solutions that other converters require. In the automotive field, the REC3-4809DRW/H4/A/SMD DC-DC converter is well-suited for powering LED lighting systems, navigation systems, and other electrical systems for vehicles. In navigation systems, the REC3-4809DRW/H4/A/SMD eliminates the need for multiple voltage conversions across the system. In energy monitoring, the REC3-4809DRW/H4/A/SMD can provide accurate output voltages for sensors and other electronic components.

The REC3-4809DRW/H4/A/SMD is an ideal choice for providing an efficient, reliable, and cost-effective solution for supplying low-voltage power sources in various applications. This small, yet powerful, DC-DC converter provides efficient current control and conversion, and eliminates the need for multiple conversions for voltage sensitive applications.
