DC DC converters have become an indispensable part of the modern power supply industry. V48SR1R225NNFA is a high efficiency 48V step-down converter, able to produce 1.2V to 38V output voltage range. It provides significantly improved system performance, shorter design cycles, and improved overall power system cost savings compared to traditional AC-DC and DC-DC designs.

The main application field of V48SR1R225NNFA consists of a wide range of industries including industrial, consumer electronics, automotive, medical, telecommunications, and aviation. It features an adjustable output voltage of 1V up to 38V, with 1V step, integrated high-side MOSFET, current protection, and thermal protection. The converters are available in metal can and SMD packages.

The working principle of V48SR1R225NNFA is relatively simple. In a boost converter, the incoming current is rectified by two diodes after which the boosted voltage is applied to the switching terminal mentioned above. The switch triggers a transistor and the energy stored in the inductor is delivered by the collector of the transistor. The output voltage is regulated with a voltage divider network. Finally, the output energy is delivered to the load.

The V48SR1R225NNFA is a highly efficient step-down converter, featuring high power output and low Ripple & Noise levels. In addition, the converter provides protection features such as current limitation and short circuit protection. The average efficiency is greater than 85%, making it suitable for high power applications. Thanks to its wide temperature range from -40°C to +125°C, the converter is also suitable for harsh environments.

At the output of the V48SR1R225NNFA, the output current is fully controlled from the primary side with the PWM modulator. This allows the converter to perform in line with various load conditions, and also compensates for variations of the input voltage.

In order to ensure optimal operation and reliability, the converter is equipped with a built-in temperature compensation circuit, which allows the peak current out of the converter to be accurately adjusted according to the temperature. This helps to improve the efficiency of the converter and makes it suitable for extreme temperature applications.

To sum up, the V48SR1R225NNFA is a highly efficient 48V step-down DC DC converter with an adjustable output voltage of 1V up to 38V, integrated high-side MOSFET, current protection, and thermal protection. This high-efficiency converter offers excellent performance in a wide variety of applications
