NCP81226 Power Management IC

The NCP81226 IC, commonly referred to by its marking 81226, is a high-performance multi-phase voltage regulator controller (VRM) from On Semiconductor (onsemi). This IC is widely used in laptop motherboards, desktop boards, and high-performance computing platforms where precise and stable power delivery is essential for modern processors.

NCP81226 is designed to manage CPU and GPU power rails, supporting efficient DC-DC voltage regulation, power sequencing, and load control under dynamic operating conditions. Its advanced control architecture helps maintain system stability, reduce power loss, and improve thermal performance. The IC is frequently replaced during chip-level motherboard repair to resolve issues such as no power, unstable booting, voltage fluctuation, or random shutdowns.

At OKSpare, all NCP81226 ICs are quality tested before dispatch. IC ready stock OKSpare ensures reliable supply from Nehru Place, Delhi.
