DC DC Converters

RW2-4805D application field and working principle

DC-DC converters are widely used in various fields. The RW2-4805D is a new generation of DC-DC converters from RICOH. It is a non-isolated buck-boost DC-DC converter module with wide input voltage range and adjustable output voltage. In addition, it is suitable for most commercial and industrial DC-DC application. The module integrally includes a low dropout voltage regulator (LDO).

Input Voltage Range

The input voltage range of the RW2-4805D DC-DC converter is 6V to 60V. This makes it suitable for applications requiring either high input voltage or low input voltage. It can also handle high surges and transient voltages. Its wide range of input voltage allows it to be used in applications powered by various sources such as solar, wind or automotive batteries.

Output Voltage Range

The output voltage of the RW2-4805D DC-DC converter module can be adjusted from 0.5 V to 50 V. This allows the module to be used in applications requiring either very low or very high output voltage. The output voltage regulation accuracy is within ±2 percent.

Wide Range of Application

The wide input and output voltage range of the RW2-4805D DC-DC converter module makes it suitable for various fields of IoT, industrial, aerospace and automotive applications. For example, it can be used to provide power for Electric Vehicle (EV) motor controller, LED lighting systems, performance audio amplifier and other automotive applications. In addition, it can also be used in industrial applications such as powering industrial process controller, microcontroller board or PLC.

Working Principle

The RW2-4805D DC-DC converter module relies on buck-boost topology. In general, it has two channels - one is for buck and one is for boost. The buck channel is used to reduce the voltage to a range of 5 to 24V. The boost channel is used to increase the voltage from 5V to 50V. The module can be switched between buck and boost with a switch.When the input voltage is higher than the output voltage, the module is in buck mode. The input voltage is reduced with the help of the inductor. The current goes through the MOSFET and the output terminal is connected to the ground. When the input voltage is lower than the output voltage, the module is in boost mode. In this mode, the MOSFET acts as a switch and the current is increased with the help of the inductor.

Conclusion

The RW2-4805D DC-DC converter is a multi-purpose low-cost converter module. Its wide input and output voltage range make it suitable for a variety of applications. It uses buck-boost conversion topology and the output voltage can be adjusted with the help of a switch. This makes it an ideal choice for industrial, automotive, aviation and other fields.
