DC/DC stands for "direct current to direct current" and refers to a category of power conversion devices that convert a DC voltage input into a different level of DC voltage output.
DC/DC converters can be found in a wide range of applications, from laptop adapters to automotive electronics. There are several types of DC/DC converters, including buck converters, boost converters, buck-boost converters, and flyback converters.
Buck converters step-down the input voltage, while boost converters step-up the voltage. Buck-boost converters can step-up or step-down voltage, depending on the input and output voltage levels. Flyback converters are commonly used in high-power applications, such as server power supplies.
DC/DC converters are essential in many electronic devices because they allow for efficient transfer of power between different voltage levels. They can also be used to isolate circuits, which is important for safety and to minimize noise and interference.
