It is suitable for many application fields including communication system, office automation, LED lighting, consumer electronics, charging station, instrumentation, medical equipment and industrial control.

Working Principle of REC3-4812DRW/H2/A/SMD

The operating principle of REC3-4812DRW/H2/A/SMD is based on synchronous buck conversion technology. When the input voltage is higher than the output voltage, the MOSFET switch is turned on to charge the inductor L1 to store the energy. At the same time, the output is powered. When the MOSFET switch is turned off, the inductor L1 releases energy to the output capacitor, thus providing a stable output voltage. At the same time, the diode D1 is turned on to transfer the energy stored in the inductor L1 to the output capacitor and realize the current circulation.

During the entire operation, the diode D1 is responsible for passing the current to the output capacitor, and the MOSFET switch is responsible for controlling the inductor\'s charging and discharging operations. The inductor L1 is responsible for the energy storage during the on period and the energy transmission during the off period. Finally, the output capacitor can smooth the output current. The operation of REC3-4812DRW/H2/A/SMD converter is controlled by the built-in PWM control circuit.
