1. What is the difference between buck-boost and buck-boost converter?
The buck converter lowers the input voltage, while the boost converter increases it. By combining both functions, the buck-boost converter can generate an output voltage that is higher or lower than the input voltage. These DC-DC converters, including the buck and boost converters, are customized for specific applications.
2. What are the different types of buck-boost?
Buck-boost converters can be classified into two types. The first type uses a single inductor and is capable of operating as either a buck or boost converter, depending on the input and output voltage. This is also referred to as a "four-switch buck-boost converter". The second type combines characteristics of both buck and boost converters, and is typically larger in size. These switch mode power supplies can step up or step down voltage levels, depending on the application.
