LM2676T-ADJ概述

    # Texas Instruments LM2676: A High-Efficiency Step-Down Voltage Regulator
    Product Introduction
    The LM2676, produced by Texas Instruments, is a monolithic integrated circuit belonging to the SIMPLE SWITCHER® family. It serves as a high-efficiency 3-A step-down voltage regulator designed for a wide range of applications requiring stable and efficient power conversion. The LM2676 supports both fixed-output versions (3.3V, 5V, 12V) and an adjustable version (1.2V to 37V), providing flexibility across multiple operational needs.
    Key features include an efficiency of up to 94%, an internal 150-mΩ DMOS output switch, and a 260-kHz fixed-frequency internal oscillator. The device operates over a wide input voltage range (8V to 40V) and ensures precise output voltage stability (+/-2%). With its robust thermal shutdown and current limiting capabilities, it's an ideal choice for systems requiring reliability and durability under extreme conditions.
