DC-DC converters, such as the RPM20-483.3SFW, are devices that convert DC power from one voltage level to another. This is done by utilizing components such as inductors, capacitors, and switches to step up or step down the voltage. DC-DC converters are used in a variety of applications, such as electronic equipment, automotive, solar power systems, industry automation, and telecommunications.

The RPM20-483.3SFW is a highly efficient, compact and highly reliable DC-DC converter. It is designed for converting 48V input voltage into 3.3V output voltage up to 20A. With a peak efficiency of 95 %, the RPM20-483.3SFW offers unmatched performance and reliability in its class.

The RPM20-483.3SFW is a buck–boost converter, which means it can convert DC power in both directions. In buck mode, the input voltage is stepped down to the output voltage and in boost mode the output voltage is stepped up to the input voltage. This makes the RPM20-483.3SFW suitable for applications where the input voltage could vary in a wide range, for example, in automotive applications, where the voltage could vary from 12V to 48V.

The RPM20-483.3SFW works in four steps. First, an active switch is opened, allowing the inductor to store energy in an AC waveform. Then, the switch is closed and the energy stored in the inductor is transferred to the load, which is connected at the output. The current then reverses direction and is rectified back into DC before passing through the output. Finally, the active switch is opened again and the cycle starts over. This 4-step cycle allows for efficient conversion of DC power while maintaining high accuracy.

The RPM20-483.3SFW offers many advantages over other DC-DC converters. It has a wide input voltage range, high efficiency, and wide ambient temperature range. Additionally, the device has many protection features such as input over-voltage, short-circuit, and over-current protection, making it ideal for use in harsh environments.
