NCP81286MNTXG

Overview:
NCP81286MNTXG is ON Semiconductor’s compact DC-DC buck regulator in the NCP family. It integrates a high-side switch and control logic to convert a higher input rail to a lower regulated output for microprocessor/FPGA rails. The MNTXG suffix denotes a small surface‑mount package suitable for compact boards.
Key features:
- Wide input range with adjustable output via a feedback network.
- High efficiency with either synchronous rectification or an external diode path.
- Automatic switching frequency with a light-load mode; fast transient response via current‑mode control.
- Protections: overcurrent/short‑circuit, overtemperature, undervoltage lockout, and fault protection.
- Simple interface: VIN, GND, VOUT, FB, EN/SHDN, plus external components (inductor, capacitor, resistor divider).
Applications:
- Power rails for CPUs/GPUs/FPGA, embedded processors; mobile and compact systems.
Note:
For exact specs (VIN range, VOUT range, efficiency, max current, pinout) consult the NCP81286MNTXG datasheet and application notes.
