LM2679SX-12/NOPB TI Step-Down Regulator | TO-263 | 12V Output, 5A

Product Overview

The LM2679SX-12/NOPB from Texas Instruments is a high-efficiency step-down (buck) switching voltage regulator capable of delivering up to 5A of load current. It features a fixed 12V output voltage and operates over a wide input voltage range from 8V to 40V. The device is housed in a TO-263 (DDPAK-7) package, offering excellent thermal performance for demanding applications. With a switching frequency of 260 kHz, it provides a good balance between efficiency and component size. The LM2679 series is part of the SIMPLE SWITCHER® family, known for ease of use and minimal external components.
