Datasheet in PDF format, 301 KB, for the AON6552 from Alpha and Omega Semiconductor. AON-prefixed parts are power MOSFETs in DFN 5x6 packages, often used as high-side or low-side switches in notebook voltage regulators. The sheet covers the pin arrangement, ratings, on-resistance and thermal performance. Technicians refer to it when a VRM rail reads shorted to ground, to confirm which pads to measure and to pick a replacement. Confirm the marking on the chip, as AOS uses abbreviated codes.
