The document discusses different types of DC-DC converters, including step-down buck converters which lower voltage, step-up boost converters which raise voltage, and buck-boost converters which can lower or raise voltage. It provides information on buck converters over pages 7-9 and step-up boost converters over pages 10-12 before discussing buck-boost converters from pages 13-15.

6. DC-to-DC Conversion
1. Step-down (Buck) converter: the output voltage of the converter is lower than the
input voltage
2. Step-up (Boost) converter: the output voltage is higher than the input voltage.
3. Step-down/step-up (Buck-Boost) converter.
