REC3-243.3SRW/H4/C

DC-DC converters are used to transfer electrical power from one DC source to another depending on input and output voltages. REC3-243.3SRW/H4/C is a type of DC-DC converter, which is designed to handle board-level power distribution applications.

The main components of this converter are an input filter, a switching regulator, a voltage-shift transformer, and an output inductor. The input filter removes any abrupt spikes in voltage and is usually a capacitor connected across the input. The switching regulator then modulates or switches the input voltage allowing for greater efficiency, output reliability and smaller size. The voltage-shift transformer enhances the voltage output and allows for power conversion. Finally, an output inductor is used in order to store energy from the switch until the supply can handle its load.

The REC3-243.3SRW/H4/C is mainly used in consumer electronics and laptops. It operates in an environment where the input voltage is less than 2.3V and the output voltage is greater than 3.3V. It has a switching frequency of 300 kHz and a power capacity of 43W. Additionally, it employs a flyback topology, meaning that its transformer has two windings; one is the primary winding and the other is the secondary winding.

The working process of the REC3-243.3SRW/H4/C starts with the input filter. The filter removes any abrupt spikes in voltage, providing a clean power supply to the circuit. After this, the switching regulator receives the filtered input voltage and modulates it according to the load demand of the circuit. This modulated feedback signal is sent to the voltage-shift transformer, which increases the voltage level of the signal. The output inductor then stores the energy from the switch until the supply can handle the load. Finally, the output voltage is adjusted to the desired level.

The REC3-243.3SRW/H4/C is a reliable and efficient DC-DC converter. Its design, which includes an input filter, a switching regulator, a voltage-shift transformer, and an output inductor, allows for remarkable power conversion results. It is mainly used in consumer electronics and laptops, and can operate in environments where the input voltage is less than 2.3V and the output voltage is greater than 3.3V. Its flyback topology further enhances its power conversion efficiency and makes it an ideal choice for any board-level power distribution application.
