LM2676S-ADJ/NOPB TI Step-Down Regulator | TO-263 | 3A, 8V-40V Input

Product Overview

The LM2676S-ADJ/NOPB is a high-efficiency step-down (buck) switching voltage regulator from Texas Instruments. It delivers up to 3A of load current with excellent line and load regulation. The device operates over a wide input voltage range of 8V to 40V and provides an adjustable output voltage from 1.2V to 37V. Housed in a TO-263 (DDPAK-7) package, it is designed for easy PCB mounting and thermal management. The LM2676 series simplifies power supply design by requiring only a few external components, thanks to its internal compensation and fixed switching frequency of 260 kHz.
