In a boost DC-DC converter, the output voltage is higher than the input voltage including in a floating boost topology where the output does not share the reference point with the input.

Boost DC-DC topologies are often used in battery-operated equipment to generate supply rails higher than the battery voltage. These designs require high-efficiency and ultra-low stand-by current as well as a small size to fit the requirements for portable and wearable devices for the Internet of Things (IoT).
