RP20-2412SFR/N Application Field and Working Principle

Introduction

The RP20-2412SFR/N is a DC-DC converter from PSU-Master, one of the best selling electronic components in China, which can be widely used in smart phones, LED lighting, medical equipment and other electrical products.

Application Fields

The RP20-2412SFR/N has many applications in many fields. In the smart phones field, it can be used to transform the Li-ion battery input to the 5V/2A USB output for charging the phones, and also to supply power for the power-saving systems in smartphones. In the LED lighting field, with its stepped down current, it could be used to reduce the amounts of current in the LED for more effective and efficient powering. In the medical equipment field, its constant voltage characteristics can help to keep the power supply to the medical equipment stable despite of the fluctuating input current from the main power.

Working Principle

The RP20-2412SFR/N DC-DC converter works on the isolated switching converter circuit, by using the transformer. The input voltage is boosted to the target voltage through the transistor switching, then the transformer would provide the needed isolation to the output end, making sure the output power has same voltage as the input one. Also because of the transformer, it allows to maximize the efficiency and minimize the size and weight of the converter.

Conclusion

Overall, the RP20-2412SFR/N DC-DC converter is a very widely used power converter with many applications in the market, and its working principle is also relatively simple and direct by using the transformer for stepping down the input voltage.
