QMB27T20090-NGB0G

DC/DC converters are widely used to convert a source of direct current (DC) from one voltage level to another. One of the most popular converters used in the industry is the QMB27T20090-NGB0G, and in this article we’ll discuss the application field and working principle of this device.

Application Field

The QMB27T20090-NGB0G converter is typically used in applications requiring the conversion of 12V to 5V DC. Examples of this include automotive applications, such as automotive lighting, vehicle security and infotainment systems, as well as industrial applications, such as HVAC systems, instrumentation, and electronic control systems. It is also used in medical equipment, such as pacemakers, defibrillators, and medical monitors. In addition, the QMB27T20090-NGB0G has been successfully used in communications, renewable energy, and military applications.

Working Principle

The QMB27T20090-NGB0G converter utilizes a switching mechanism in order to convert the source DC voltage from one level to another. It works by connecting the input voltage to an inductor, which is then connected to the output voltage in such a way that the inductor stores energy. A switch is then used to turn the power on and off, which in turn alternates the voltage to the output. The output voltage is determined by the rate of switching and the ratio of the inductor’s turns.

The QMB27T20090-NGB0G converter also uses an internal feedback circuit to regulate the output voltage. This feedback circuit senses the output voltage and adjusts the switching rate in order to maintain the desired output voltage. The converter also utilizes a synchronous rectifier to improve the efficiency of the converter by reducing the power loss associated with the rectification process. This allows the QMB27T20090-NGB0G to achieve high efficiency levels, up to 92%.

Conclusion

The QMB27T20090-NGB0G DC/DC converter is a popular choice for applications requiring a 12V to 5V conversion. It utilizes a switching mechanism in order to convert the source voltage to the desired level and an internal feedback circuit to regulate the output. The converter’s internal synchronous rectifier further improves efficiency levels, allowing it to achieve up to 92% efficiency. This makes the QMB27T20090-NGB0G an ideal choice for a variety of automotive, industrial, medical, communications, renewable energy, and military applications.
