LM2670S-5.0/NOPB TI Step-Down Regulator | TO-263 | 5V Output, 3A

Product Overview

The LM2670S-5.0/NOPB is a high-efficiency step-down (buck) switching voltage regulator from Texas Instruments. It delivers a fixed 5V output with up to 3A load current, featuring a wide input voltage range of 8V to 40V. Housed in a TO-263 (DDPAK-7) package, this device integrates a 260kHz oscillator, internal compensation, and a high-side N-channel MOSFET, simplifying design and reducing external component count. The LM2670 series is part of the SIMPLE SWITCHER® family, known for ease of use and robust performance.
