The output voltage is adjustable between 0.9 to 15 VDC, with an output current rating of up to 4A. The device features a high efficiency, up to 94%, making it an ideal choice for applications requiring low standby power consumptions.

Application Fields

The REC3-2409SRWZ/H6/A/SMD is widely used in applications such as laptops, portable medical devices, industrial equipment, factory automation, educational and automotive electronics, utility meters, and more. It is suitable for a variety of applications where a high-efficiency, low-cost, wide-input voltage range DC-DC converter is needed.

Working Principle

The REC3-2409SRWZ/H6/A/SMD DC-DC converter is designed with a synchronous buck-boost switching regulator. This switching regulator consists of two input capacitors, two inductors, one output capacitor, and two pairs of transistors, working in parallel and operating at different frequencies. The input DC voltage is first rectified to pulsating DC voltage by the input capacitors. The inductors take the pulsating DC voltage and step up or step down the voltage according to the switching frequency set in the circuit.

The transistors then switch on and off according to the signal from the controller. This process creates an output voltage that is regulated according to the feedback control signal, which the controller uses to adjust the output voltage to the desired level. The output capacitor then smooths out the pulsing voltage to create a steady DC output voltage. The overall process helps to reduce power loss and increase the efficiency of the converter.

Conclusion

The REC3-2409SRWZ/H6/A/SMD DC-DC converter is a high-performance, cost-effective device that is suitable for a wide range of applications. Its synchronous buck-boost switching regulator design helps to maximize efficiency and reduce power loss. The adjustable output voltage and high current rating make it a great choice for applications that require a reliable DC-DC converter with a wide range of input and output voltage levels.
