LMQ66420MC3RXBRQ1 TI Buck Converter | 14-VQFN (2.6x2.6) | 36V, 2A, Low EMI

Product Overview

The LMQ66420MC3RXBRQ1 is a high-performance, low-EMI step-down (buck) converter from Texas Instruments, designed for automotive and industrial applications. It operates from a wide input voltage range of 3V to 36V, delivering up to 2A 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 integrated MOSFETs, advanced EMI reduction features, and a switching frequency of 2.2MHz, the LMQ66420MC3RXBRQ1 simplifies power supply design while meeting stringent automotive EMI requirements.
