Design Notes
- Buck-boost operation keeps the output regulated either side of the input, which costs efficiency compared with a pure buck at the same rating.
- Power switches are integrated, so the thermal path is the PCB copper under the pad.
- Package QFN-32 — check the land pattern in the datasheet before layout.
