NCP81074AMNTBG

NCP81074AMNTBG is ON Semiconductor’s high-efficiency, synchronous buck DC-DC regulator. It’s designed to convert a higher DC input to a stable, adjustable lower output for power rails in CPUs, GPUs, FPGAs, and other digital ICs.
Key points:
- Integrated high-side and low-side MOSFETs for a compact, efficient step-down converter.
- External feedback network sets the output voltage; supports programmable switching frequency.
- Protection and reliability: overcurrent/short-circuit protection, thermal shutdown, undervoltage lockout, and soft-start.
- Packaging: AMNTBG suffix denotes an 8-pin RoHS-compliant package (with tape-and-reel option).
Common usage:
- Provide core rails for processors and ASICs; used in VRM-like power-management designs.
- Requires typical buck components (inductor, input/output capacitors, feedback resistors) per the datasheet reference design.
For exact electrical specs (input range, maximum output current, switching frequency, efficiency, pinout), consult the official NCP81074 datasheet and product page.

QFN-16 package: 3×3 mm footprint with an exposed pad (16-pin, low-profile package).

- Pin count: 48 pins (QFN package).
- Function: Four‑phase synchronous buck PWM controller (VRM) with integrated gate drivers, current sensing, enable/soft‑start, and fault protection for CPU/GPU core voltage regulation.

Manufacturer: ON Semiconductor (onsemi).
What kind of company: A global American semiconductor company that designs, manufactures, and markets energy-efficient integrated circuits and power-management devices.
