Buck boost converter
Buck-boost converters produce a regulated output voltage either less than or greater than the input voltage when the input voltage is higher than the output, the converter acts as a buck when the input is lower than the output, the converter boosts two simple formulae determine the current rating of the inductor.

Supporting up to 3 a of operating current, st's single-inductor synchronous buck-boost converters integrate four low on-state resistance power mosfets which contribute to pcb saving and reduced power losses, making them ideal for li-ion battery-powered applications. The buck-boost converter is a type of dc-to-dc converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude it is equivalent to a flyback converter using a single inductor instead of a transformer.
The buck converter is a very simple type of dc-dc converter that produces an output voltage that is less than its input the buck converter is so named because the inductor always bucks or acts against the input voltage.
