概述

Description

NCP81286MNTXG is an ON Semiconductor DC-DC switching regulator (buck converter) from the NCP8128x family. It’s designed for compact point‑of‑load power regulation in applications such as embedded systems, CPUs/GPUs, memory, and telecom gear. The device comes in an 8‑pin MNTXG package and provides adjustable output via an external feedback network, targeting high efficiency and small footprint. Typical features include protection functions (e.g., overcurrent/overtemperature/undervoltage), and suitability for low quiescent current operation across load conditions. It’s intended for use with an external inductor and other passive components to form a complete step‑down regulator. For exact electrical specs—input voltage range, output voltage options, maximum load current, switching frequency, and package details—consult the official datasheet/product page.

Features

I don’t have real-time access to the exact datasheet, but typical features for NCP81286MNTXG (ON Semiconductor) include:
- High-efficiency step-down regulator with integrated high-side MOSFET
- Wide input voltage range
- Adjustable output via external feedback resistors
- Fixed-frequency PWM/current-mode control
- Enable/UVLO input
- Soft-start to limit inrush
- Overcurrent/short-circuit protection
- Over-temperature shutdown with automatic restart
- Small 8-pin package (MNTXG) and RoHS-compliant/tape-and-reel packaging
For precise electrical specs (voltage ranges, switching frequency, current limit, etc.), please refer to the official datasheet.
