概述

Description

NCP3020ADR2G is ON Semiconductor’s high‑efficiency buck (step‑down) DC‑DC regulator that integrates a power MOSFET with a PWM controller for a compact point‑of‑load regulator. It supports fixed or adjustable output via external feedback, a wide input voltage range, and a programmable switching frequency. Protective features include undervoltage lockout, current limit, overtemperature shutdown, and soft‑start. The ADR2G package offers a small, surface‑mount footprint suitable for tight PCB layouts. Typical uses are post‑regulation for CPUs/GPUs, battery‑powered systems, and other consumer electronics requiring efficient, compact DC‑DC conversion. For exact specs (input range, max output current, efficiency, pinout), refer to the official NCP3020ADR2G datasheet on ON Semiconductor’s website.

Package

NCP3020ADR2G is in an 8-pin SOIC (small-outline) RoHS package.

Pinout

I don’t have the datasheet handy, but the NCP3020ADR2G is an 8-pin device in the ADR2G package. It functions as a DC-DC buck regulator (buck converter) with an integrated high-side switch; typical pins include VIN, GND, LX (switch node), EN, FB, and related control pins. For exact pinout and pin functions, please consult the ON Semiconductor datasheet.
