MP2941BGL-Z MP2941B MPS IC Marking MPKH MPNY MPMZ MPJG MPKH is a high-performance digital multi-rail voltage controller IC designed for modern Intel and AMD laptop platforms. It provides precise regulation for CPU, GPU, system agent (SA), and auxiliary VRM domains, making it ideal for high-efficiency gaming laptops, ultrabooks, and workstation motherboards. This controller offers excellent load regulation, low ripple, and stable multi-phase operation under demanding workloads.The MP2941BGL-Z (MP2941B series) also functions as a 4-phase programmable GPU voltage controller, fully pin-to-pin compatible across MP2941B variants. It is widely used in dedicated GPU rails on MXM and PCIe dGPU power sections, capable of delivering 20–50A when combined with external MOSFET power stages.
The MP2941B family is identified by genuine MPS codes such as MPKH, MPNY, MPMZ, and MPJG,
