NCP302155A Power Management IC

The NCP302155A Power Management IC from onsemi is a high-integration DC-DC buck converter IC that combines a high-side MOSFET, low-side MOSFET, and gate driver into a single compact package. This design allows efficient high-current power conversion while reducing external component count and board space.

The NCP302155A is widely used in laptop motherboards, graphics cards, embedded systems, industrial electronics, and high-performance power circuits, where stable voltage regulation and fast transient response are required. It plays a key role in supplying power to CPUs, GPUs, memory rails, and core logic circuits.

At OKSpare, all NCP302155A ICs are quality tested by the OKSpare team before dispatch to ensure reliable performance. IC ready stock OKSpare supports technicians, service centers, and bulk buyers with trusted supply from Nehru Place, Delhi.
