It is a expenive and too complicated for just a true shutdown.

It is not a very difficult design if FET is allowed to be added in the power path. Many new boost converters indeed manipulate the P-Well of the synchronous switch (yes, the solution is only suitable for synchronous boost converter) so that the body diode is eliminated when the part is in shut down. This can improve the overall efficiency and save you board space.

Any technical document about this true shutdown circuit? E.g. how can we use it for our own designs?
