NCP81220 Dual Rail PWM VRM Controller IC

The NCP81220 IC from On Semiconductor (onsemi) is an advanced dual-rail, 4+2 phase dual-edge modulated multiphase PWM controller designed for high-performance CPU and GPU power management. This IC is widely used in laptop motherboards, desktop systems, graphics cards, and high-performance embedded platforms, where accurate and efficient power delivery is essential.

NCP81220 manages multiple power rails simultaneously, providing precise voltage regulation, load balancing, and stable power sequencing for demanding processors and chipsets. Its dual-edge modulation architecture improves efficiency and transient response, helping maintain system stability under dynamic load conditions. The IC is commonly replaced during chip-level motherboard repair for issues such as voltage instability, no-boot conditions, or power rail faults.

At OKSpare, all NCP81220 ICs are quality tested before dispatch. IC ready stock OKSpare ensures trusted supply from Nehru Place, Delhi.
