QSB10048S3V3

DC-DC Converters

DC-DC converters are an indispensable tool for transferring power from one DC voltage source to another. They are commonly used to power microprocessors, LED lights, and other low-power devices which require a different voltage level than the source. The QSB10048S3V3 is a type of DC-DC converter specifically designed for a wide range of applications, such as providing precise voltage regulation, low output ripple, and high efficiency. This article will explain the different application fields and working principles of the QSB10048S3V3.

Application Fields

The QSB10048S3V3 is suitable for powering devices which consume up to 48 W of steady-state power. It is particularly suitable for applications where the input voltage varies significantly, such as when a solar panel is used as the source of the power. In such cases, the QSB10048S3V3 will ensure that consistent power levels are maintained, regardless of the changing input voltage. The converter is also suitable for use in tight spaces, as it only occupies a small footprint, measuring 62.5 x 25.4 x 11.2 mm.

Because of its high-efficiency design, the QSB10048S3V3 is also perfect for powering heat-sensitive devices, such as CCD cameras or other sensitive imaging equipment. The converter features a wide input voltage range between 4.5V and 36V, and output voltages ranging from 1–27.6V, allowing it to be used for a variety of tasks.

Working Principle

The working principle of the QSB10048S3V3 is based on switching one voltage level to another. To achieve this, the converter utilizes a Buck-Boost topology with a power switch inside it. That switch is used to replace the power supply of the component and control the voltage level at the output. The control loop monitors the output voltage and adjusts the power switch to ensure that the voltage is maintained.

The converter also features other advanced functions, such as over-voltage protection, over-current protection, short-circuit protection and thermal protection, which are essential for protecting the device and the system from abnormal voltages. Additionally, the converter offers high efficiency with up to 95% when the load is 20-100%.

Conclusion

The QSB10048S3V3 is a DC-DC converter designed to transfer power from one voltage source to another with precision. It can handle a wide range of input voltages and is suitable for applications where precise voltage regulation is needed. It offers high efficiency and is also equipped with advanced protection features, making it an ideal solution for powering sensitive and heat-sensitive devices. Whether you are looking for a reliable DC-DC converter for powering your microprocessor or LED lights, the QSB10048S3V3 is the perfect choice.
