概要
Description
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.
