Working Principle of QM48T50025-NCC0

The QM48T50025-NCC0 DC DC converter follows the buck-boost topology. This type of switching power supply uses an inductor as the primary energy-storage element. Primary energy is stored in the inductor during the on-time of the switches, and it is released when the switches are off. In buck-boost topology, the switching frequency of the drivers is kept constant which increases efficiency and stability.

The efficiency of DC-DC conversion can be improved by optimizing the on-time of the switches, as well as by a careful design of the inductor. The QM48T50025-NCC0 is equipped with an integrated current mode controller, which allows the converter to remain in the continuous-conduction mode over the entire input voltage range. This results in higher efficiency, lower noise, and reduced losses.

The QM48T50025-NCC0 also features protection functions such as short-circuit protection, over-voltage protection, and under-voltage protection. These functions are designed to protect the converter from damage due to overload or excessive input or output voltages. Additionally, the integrated over-temperature protection ensures a safe operation of the converter at high temperatures.

Conclusion

QM48T50025-NCC0 is a series of high-performance DC-DC converters that provide an efficient solution for a wide range of applications. It is suitable for automotive, industrial, and harsh environment applications, and it is equipped with a variety of protection functions for added safety. The DC DC converter follows the buck-boost topology with an integrated current mode controller, which ensures high efficiency and stability of the power conversion.
