LM22673QTJE-ADJ/NOPB TI Adjustable Step-Down Regulator | TO-263-7 Thin | 42V, 3A

Product Overview

The LM22673QTJE-ADJ/NOPB is a high-performance adjustable step-down (buck) voltage regulator from Texas Instruments. It features an input voltage range of 4.5V to 42V and delivers up to 3A of continuous output current. The device is housed in a thin TO-263-7 package, making it suitable for space-constrained applications. With an adjustable output voltage from 1.285V to 37V, it provides design flexibility for various power supply requirements. The regulator integrates a high-side N-channel MOSFET and operates at a fixed switching frequency of 500 kHz, enabling small external components.
