This DC-DC converter is also ideal for applications where space is limited, due to its small footprint.

Working Principle

The REC3.5-1224SRW/R10/A/CTRL is a Switch-Mode Power Supply (SMPS) based DC-DC converter. It operates on the principle of converting a DC input voltage into a DC output voltage, with the help of an inductor. The converter consists of a transformer, rectifier, and inverter, all integrated into a compact, surface-mountable package. The transformer acts as an AC voltage transformer, able to adapt to a wide input voltage range. The input AC voltage is then rectified to obtain a DC voltage, which is then used as the input to the converter. The converter then uses a series of switches to control the flow of the current, transforming the input voltage to an output voltage.

The transformer isolates the input and output of the converter, ensuring that the output voltage does not rely on the input voltage. This ensures system reliability and stable operation over the entire input voltage range. Additionally, the integrated EMI filters protect the system by blocking any high frequency signals that may be present in the DC- DC conversion.

The integrated current-mode control technology and over-voltage protection circuitry provides a secure and stable output voltage and current, regardless of whether the input voltage is rising or dropping. Additionally, the converter has a built-in temperature-controlled cooling fan for improved heat dissipation. This allows the converter to have excellent thermal efficiency, providing reliable power delivery over long periods of time.

In conclusion, the REC3.5-1224SRW/R10/A/CTRL is a highly efficient and reliable DC-DC converter, designed for a wide variety of applications. It has a wide input voltage range, making it ideal for system processors, gate drivers, and relays. Additionally, the integrated EMI filter circuitry, current-mode control technology, and temperature-controlled cooling fan provide stable and reliable operation, ensuring a longer lifetime and maximum power output. This DC-DC converter is ideal for applications where space is limited, due to its small footprint and high efficiency.}
