DC-DC converters are suitable for many applications in the field of energy efficiency, and the R2S12-0515/HP-R is one of the most important of these components. The R2S12-0515/HP-R is a high-power DC-DC converter with outstanding performance characteristics and features.

R2S12-0515/HP-R has rated output power of 200A, efficient conversion efficiency up to 92%, and working frequency up to 33KHz. Its input voltage range is 4.5 to 14.5V and its output voltage range is 0.6 to 5.5V. This device has regenerative technology to enhance power supply efficiency, reduce EMI and output ripple, and protect components from overvoltage. It also has overcurrent protection, low standby current, and fast transient response.

The working principle of the R2S12-0515/HP-R is based on reverse current-mode control. This device output voltage is proportional to the feedback voltage signal from the FB pin on the device. With the feedback voltage signal, the input voltage will be deprived of a certain value, usually around 1.3V and the current will reverse overshoot, the voltage spikes will be in the direction of feedback voltage, it changes the output voltage to target in high speed. When the power input voltage is lower than the voltage on the FB pin, the pass transistor will close and there will be no output current for the load. When the output current reaches the current limit value, the internal current will be controlled like the voltage, and the output current is limited, so the output current is constant.Besides the output voltage, the R2S12-0515/HP-R also provides temperature protection to protect the converter from overheating. The R2S12-0515/HP-R has wide application fields such as AC/DC power supply, LED lighting, battery charger, brushless motors, industrial control systems and power management, etc. Overall, the R2S12-0515/HP-R is a well-designed DC-DC converter with excellent performance, reliability and protection features. It is suitable for many applications and can offer great efficiency and power savings.
