NCP81074AMNTBG

NCP81074AMNTBG is a synchronous buck DC-DC converter from ON Semiconductor (NCP8107x family). It steps down a higher input voltage to a stable, low-voltage rail for digital logic in compact, battery-powered devices. The device integrates high-side and low-side MOSFETs, uses PWM current-mode control, and provides protections and status signals typical of small power regulators.
Key features (high level):
- Input range: suitable for battery/single-supply systems (common 2.5–5.5 V)
- Adjustable output via external feedback resistors (typical range ~0.8–3.3 V)
- En/Power-Good, soft-start, and protection features (overcurrent/short-circuit, thermal shutdown)
- High efficiency with MHz-range switching frequency, enabling smaller inductors and caps
- 8-pin, RoHS/lead-free package variant (AMNTBG)
Common applications:
- Portable electronics, MCU/SoC core supplies, wearables, sensors, telecom modules
Note: For exact electrical characteristics (voltages, currents, timing), refer to the official datasheet.

Pin count: 8 pins (8‑lead package, e.g., MSOP/SOIC).
Function: NCP81074AMNTBG is an 8‑pin DC‑DC regulator controller/Power Management IC used to regulate voltage in switching regulator applications (buck regulator).

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation)
- What kind of company: A multinational American semiconductor company that designs, manufactures, and sells energy-efficient ICs and other semiconductor components for automotive, industrial, consumer, and computing markets.

NCP81074AMNTBG is used as a multi‑rail voltage regulator solution (VRM) for power management in digital systems. Typical application areas include:
- CPU/GPU/FPGA/ASIC core voltage regulation
- Server, workstation, and data‑center boards
- Desktop and laptop (notebook) motherboards
- Networking, telecom, and datacom equipment
- Embedded industrial, automotive, and mixed-signal systems requiring multiple regulated rails with high efficiency
In short: compact, multi‑output buck regulator solutions for modern multi‑rail power architecture.

NCP81074AMNTBG is in an 8-pin WSON package (2×2 mm), RoHS-compliant (BG).
