CQS48025-45-R

DC-DC converters are a type of power converter that converts direct current (DC) from one power source to another, usually to alter the voltage of a source for use in applications. One of the most commonly used DC-DC converters is the CQS48025-45-R, which is widely used in a variety of applications due to its high efficiency, small footprint, and versatile design.

The CQS48025-45-R is a step-down DC-DC converter designed for use in devices that require a regulated power source, typically within the range of 4.5 to 17V DC power. In other words, it is capable of taking an input voltage of up to 17V DC and converting it to a lower and more stable output voltage. The CQS48025-45-R has an input voltage range of 4.5 - 17V, and is capable of converting down to a regulated output of 3.3V in some applications, though the output voltage range can be adjusted by changing jumpers on the PCB.

The CQS48025-45-R converter works by rectifying the input voltage to a steady DC, and then passing the DC voltage through a switching regulator which is made up of an inductor, a diode, a stray capacitor and the switching FET. The switching FET is the key element in controlling the output voltage of the device, and is controlled by an internal control circuit. The control circuit manages the pulsing frequency of the FET, which is determined by the input voltage and other factors. By regulating the pulse width of the FET, the output voltage of the device can be adjusted to the desired level.

The CQS48025-45-R DC-DC converter is a popular choice for many applications where a reliable, efficient power source is needed. It is commonly used in automotive electronics, medical devices, consumer electronics, and various other applications. Its small footprint and high efficiency make it a great option for designers looking to minimize their PCB footprint while maximizing their power efficiency. In addition, its internal control circuit allows for easy customization of the controlled power output for specific applications.

Overall, the CQS48025-45-R DC-DC converter is a versatile and reliable power source for a wide variety of applications. Its high efficiency, small footprint, and adjustable output voltage make it a great choice for those looking for an easy to use power source that will reliably supply their devices with the needed power.
