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.
• AEC-Q100 qualification suits this part to automotive rails.
• Package QFN-27 — check the land pattern in the datasheet before layout.
