LM62440ALPQRJRRQ1 TI Buck Converter | 14-VQFN-HR (4x3.5) | 4A, 2.1MHz

Product Overview

The LM62440ALPQRJRRQ1 is a high-performance synchronous buck converter from Texas Instruments, designed for automotive and industrial applications. It integrates high-side and low-side MOSFETs to deliver up to 4A continuous output current. With a wide input voltage range of 3V to 36V, it supports 12V and 24V bus systems. The device operates at a fixed 2.1MHz switching frequency, enabling small external components and a compact solution size. The 14-VQFN-HR (4x3.5mm) package offers excellent thermal performance for space-constrained designs.
