Working Principle of REC5-4812SRW/H6/C/SMD

This REC5-4812SRW/H6/C/SMD DC-DC converter module utilizes a Flyback transformer for power conversion. The Flyback topology is based on a coupled inductor, where energy stored in one of the two inductors is transferred to the other. The primary coil of the transformer is connected across the input voltage and the secondary is connected across the output voltage. The core of the transformer houses two diodes which facilitate current direction when the switch is flipped. The connection of the secondary diodes is configured in such a way so that the output voltage polarity will always remain unchanged.

The REC5-4812SRW/H6/C/SMD DC-DC converter module uses a control IC to regulate the operation of the power conversion cycle. The control IC provides feedback to the power switching device, which is a power MOSFET, and controls the operation of the transformer. If the output is overloaded or shorted, the control IC will detect the condition and send a signal to the MOSFET to stop the operation of the transformer till the overload or short circuit is removed. When the output is normal, the control IC will start the operation of the switch again to regenerate the output voltage.

The REC5-4812SRW/H6/C/SMD DC-DC converter module also boasts a unique isolated thermal path feature, which allows the converter to dissipate more heat and thereby increase power efficiency. Additionally, it has an integrated input EMI filter, which helps reduce the amount of conducted interference signals that are admitted into the primary input.
