The NB685GQ-Z NB685G AKU* MPS IC Marking AKUF AK1D AKUM AKUG AKUX26V, is a compact and efficient 12A synchronous buck regulator with an integrated ±1A LDO and VTTREF output designed for DDR4/DDR5 memory power rails. It comes in a QFN-16 3×3 package and is widely used in modern gaming laptops such as HP Omen 16, MSI GE76, Acer Nitro, and other high-performance boards requiring accurate DDR termination.
This AKU-series IC is identified by genuine MPS factory top markings like AKUF, AK1D, AKUM, AKUG, and AKUX, all belonging to the AKU* marking family. These markings confirm correct NB685GQ-Z identification and batch authenticity across different motherboard models.
Engineers use this IC to repair DDR VDDQ/VTT/VREF rail failures, boot loop issues, memory no-detect faults, and unstable DDR voltage conditions.
