All the time sufficient voltage is available at the input, the input is connected directly (with no regulation) to the output to feed the load and a buck converter ... but with the boost converter ...

and how they can be integrated into a non-inverting buck-boost converter. He further simplifies that circuit into an inverting buck-boost, and sets about explaining the limitations of the circuit.

As it turns out, yes there is, and [Shahriar] at The Signal Path walks us through a basic circuit to reduce noise from DC-DC converters. The module under the knife is a popular buck-boost ...
