This device features 4.9-14.5 VDC input voltage range, and the output is adjustable from 1.2-5.5 VDC. It has a wide input range, low noise, and high efficiency.

REC5-4809DRWZ/H4/A/SMD Application Field

The REC5-4809DRWZ/H4/A/SMD is a versatile, low-profile, high-efficiency device and is ideal for a variety of applications. It can be used in industrial and telecommunications equipment, vehicle control systems, gaming systems, and medical equipment and a variety of other industrial and automotive applications.

REC5-4809DRWZ/H4/A/SMD Working Principle

The REC5-4809DRWZ/H4/A/SMD DC-DC converter uses buck topology and a control circuit to reduce its input voltage to the pre-set output voltage. It uses a power stage comprised of a power MOSFET to facilitate the current flow from the input source to the output, and a control circuit to regulate the voltage to the predetermined output voltage. The amount of power that is delivered to the load depends on the control of the MOSFET and the current flow in the inductor. When the switch is turned on, the power is delivered through the power stage to the output in the form of current. When the switch is turned off, the diode allows the current to continue to flow in the inductor for a short amount of time, thereby creating a voltage drop and allowing the charge to return to the power source. This is how the circuit is able to maintain a steady output voltage in spite of variations in the input voltage.

Conclusion

The REC5-4809DRWZ/H4/A/SMD DC-DC converter is an ideal choice for a variety of applications due to its wide input range, low noise, and high efficiency. It is used in a variety of applications, including industrial and telecommunications equipment, vehicle control systems, gaming systems, and medical equipment. It uses buck topology and a control circuit to reduce the input voltage to the pre-set output voltage. The power stage is comprised of a power MOSFET, and the control circuit regulates the voltage to the pre-determined output voltage.
