LMQ66430MA3RXBRQ1 TI Buck Converter | 14-VQFN (2.6x2.6) | 3A, 36V

Product Overview

The LMQ66430MA3RXBRQ1 is a high-performance synchronous buck converter from Texas Instruments, designed for automotive and industrial applications. It operates over a wide input voltage range of 3.5V to 36V and delivers up to 3A of continuous output current. Housed in a compact 14-pin VQFN package (2.6mm x 2.6mm), this device integrates high-side and low-side MOSFETs, minimizing external component count and solution size. The LMQ66430MA3RXBRQ1 features a fixed 2.2MHz switching frequency, enabling small inductor and capacitor values, and supports pulse-skip modulation for high efficiency at light loads.
