DC-DC converters are used to convert DC power from one source to another, such as from a battery or a solar panel to a higher voltage. The CQ2001-7R is an example of such a device, used to convert a lower DC voltage to a higher voltage. In this article, we\'ll discuss its application field and working principle.

The CQ2001-7R is a non-isolated step-up (boost) converter, which means that it takes DC power from an input source (e.g. a battery or a solar panel) and raises the voltage to a higher voltage. The output voltage can be adjusted, and it can be used for anything from powering small gadgets to running electric motors or other large load appliances.

The CQ2001-7R is typically used in applications where the input voltage may not necessarily be constant; for example, when using a solar panel, the voltage can vary due to changing sunlight levels. The device can also be used for voltage conversion in regenerative braking systems, where the input power needs to be adjusted in order to properly match the output voltage from the motor.

In terms of operation, the CQ2001-7R works by adjusting the duty cycle of a switching transistor, which converts the input voltage to a higher output voltage. The device uses pulse width modulation to vary the duty cycle of the transistor, and also includes protection features such as over voltage, over current, short circuit, and over temperature protection.

Since the CQ2001-7R is not an isolated device, it does not contain any filters or transformers, which makes it extremely efficient and small in size. It is capable of outputting up to 3.0A of current, and has a wide input voltage range (4.75V-18V). This makes it an ideal choice in many applications where a small size and high power efficiency is desired.

In conclusion, the CQ2001-7R is a DC-DC converter used to convert lower DC voltages into higher voltages, used in a variety of applications from powering small gadgets to running electric motors or other large load appliances. It works by adjusting the duty cycle of a switching transistor, and is highly efficient and small in size.
