LM64440CPPQRYFRQ1 TI Buck Converter | 22-VQFN-HR (3.5x4) | 36V, 4A, 2.2MHz

Product Overview

The LM64440CPPQRYFRQ1 from Texas Instruments is a high-performance synchronous buck converter designed for automotive and industrial applications. It operates from a wide input voltage range of 3.5V to 36V, delivering up to 4A continuous output current. The device features a compact 22-pin VQFN-HR package (3.5mm x 4mm) with enhanced thermal performance. With integrated high-side and low-side MOSFETs, the LM64440 achieves high efficiency and reduces external component count. The switching frequency is programmable from 200kHz to 2.2MHz, allowing optimization between efficiency and solution size. Advanced features include frequency spread spectrum for EMI reduction, power-good indicator, and adjustable soft-start. The device is AEC-Q100 qualified for automotive applications.
