LM2677S-ADJ/NOPB TI Step-Down Regulator | TO-263 (DDPAK-7) | 8A, 1.2-37V

Product Overview

The LM2677S-ADJ/NOPB is a high-efficiency step-down (buck) switching voltage regulator from Texas Instruments. It is part of the SIMPLE SWITCHER® series, designed to deliver up to 8A of output current with excellent line and load regulation. The adjustable output voltage can be set from 1.2V to 37V using external resistors. Housed in a TO-263 (DDPAK-7) package, this device integrates a 260 mΩ N-channel MOSFET switch, enabling high efficiency and minimal external component count. The LM2677 operates at a fixed 260 kHz switching frequency, allowing for small filter components. It features a wide input voltage range of 8V to 40V, making it suitable for various industrial and automotive applications.
