LMQ66410MA5RXBRQ1 TI Buck Converter | 14-VQFN (2.6X2.6) | 36V, 1A, Low IQ

Product Overview

The LMQ66410MA5RXBRQ1 is a high-performance step-down (buck) DC-DC converter from Texas Instruments, designed for automotive and industrial applications. It operates over a wide input voltage range of 3V to 36V and delivers up to 1A of continuous output current. The device is housed in a compact 14-pin VQFN package measuring 2.6mm x 2.6mm, making it ideal for space-constrained designs. With ultra-low quiescent current (IQ) of 2.5µA (typical) in sleep mode, it significantly extends battery life in always-on systems. The LMQ66410MA5RXBRQ1 integrates high-side and low-side MOSFETs, requires minimal external components, and offers excellent transient response and efficiency.
