RP20-4812SF-HC

The RP20-4812SF-HC is a DC-DC converter of pulse width modulation (PWM) from Recom Power. This device is an isolated part designed for 250W, 48V-12V applications, and with a 5:1 input voltage range and an efficiency to up to 90%. The type of technology used in this device is High Current Synchronous Buck

The application fields of the RP20-4812SF-HC are mainly for output-current limited applications including telecommunications, industrial electronics and distributed power architectures. This DC-DC Converter also has a wide range of input voltage from 36 up to 160V, making it suitable for distributed power systems, telecoms, servers and industrial electronics.

The working principle of the RP20-4812SF-HC is based on a PWM control scheme. The network communication among the different components, enables the system to automatically identify the best PWM parameters for optimal efficiency and the most linear performance. When the strong-side MOSFET switch is on, the input voltage can charge the inductor. When the output voltage has reached the reference level, the strong-side MOSFET switch turns off and the weak-side MOSFET turns on, which will discharge the stored energy by the inductor to the output capacitor. The output then becomes steady at the set value.

In addition, the RP20-4812SF-HC has a high efficiency of up to 90%. This allows it to offer very low power dissipation and low heat generation. The converter also has low ripple and noise due to integration of a state-of-the-art linear regulator and power supply. This makes it suitable for applications that are sensitive to noise.

To sum up, the RP20-4812SF-HC DC-DC Converter is designed for 250W, 48V-12V applications and with a 5:1 input voltage range. It is suitable for output current limited applications in telecommunications, industrial electronics and distributed power architectures. It has a wide range of input voltage from 36 to 160V and also a high efficiency of up to 90%.
