The NB676AGQ-Z from Monolithic Power Systems is a compact 21V, 8A COT synchronous buck regulator. It is engineered for high-current system rails, commonly found in modern gaming laptops. This IC operates at a fixed or high switching frequency, making it suitable for compact motherboard layouts.
This regulator is frequently utilized for robust 5V high-current rails in performance laptops, such as the Lenovo Legion Slim and ASUS TUF A17 RTX 4070 series. The NB676AGQ-Z is identified by specific MPS top markings like AKLD, AKLG, AKLE, AKLF, and AKLX, which are part of the AKL* marking family exclusively for the NB676AGQ-Z batch. These markings aid engineers in confirming the correct IC and preventing confusion during gaming motherboard repairs.
Technicians commonly employ this IC to address issues such as 5V rail drop, no power, auto-restart, unstable loads, and VRM heating problems. The device comes in a QFN-16 (3x3mm) package, designed for surface mount applications.
