LMQ62440APPQRJRRQ1 TI Step-Down Converter | 14-VQFN-HR (4x3.5) | 36V, 4A

Product Overview

The LMQ62440APPQRJRRQ1 is a high-performance step-down (buck) DC-DC converter from Texas Instruments, designed for automotive and industrial applications. It operates from a wide input voltage range of 3V to 36V and delivers up to 4A of continuous output current. The device is housed in a compact 14-pin VQFN-HR package (4mm x 3.5mm) with enhanced thermal performance. With integrated MOSFETs, low quiescent current, and a switching frequency up to 2.2MHz, it provides high efficiency and small solution size.
