LM2670T-ADJ/NOPB TI Simple Switcher | TO-220-7 | 3A, 8V-40V

Product Overview

The LM2670T-ADJ/NOPB is a high-efficiency, 3A step-down (buck) switching regulator from Texas Instruments' Simple Switcher family. It 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-220-7 package, this device integrates a 260 mΩ N-channel MOSFET and requires minimal external components, simplifying design and reducing board space. With a fixed switching frequency of 260 kHz, it offers excellent line and load regulation, making it suitable for a variety of power conversion applications.
