Working Principle

The working principle of DC-DC converters is based on converting DC voltage from one level to another level. In this case, the SQM48T25012-NAB0 DC-DC converter can take input voltage from 12V to 48V and then convert it to a regulated 5V output with high accuracy.

The working of this model involves a two stage process. In the first stage, the transistors switch on and off thousands of times a second to form a high frequency oscillating waveform. This waveform is then converted to the output voltage with the help of an inductor and a capacitor. In the second stage, a feedback circuit works to maintain the output voltage level by monitoring the output voltage and adjusting the switch duty cycle and frequency appropriately.

The SQM48T25012-NAB0 DC-DC converter has a step-down switching frequency of up to 400KHz and features short circuit, over-current, over-voltage and over-temperature protection. Its high efficiency and low ripple reduce heat generation, which increases the system reliability and reduces noise.

Conclusion

The SQM48T25012-NAB0 is an advanced DC-DC converter, which is suitable for a wide range of applications. Its key features are high level of regulation accuracy, high peak current capability, and the capability to work in harsh environments. Its working principle is based on two stages involving a high-frequency switch and a feedback circuit. Finally, its high efficiency and low ripple reduce heat generation and ensure improved reliability and reduce noise.
