LMR33630CRNXR TI Step-Down Converter | 12-VQFN-HR (3x2) | 36V, 3A, 2.2MHz

Product Overview

The LMR33630CRNXR from Texas Instruments is a high-performance, synchronous step-down (buck) DC-DC converter designed for industrial and automotive applications. It operates over a wide input voltage range from 3.8V to 36V, delivering up to 3A of continuous output current. The device integrates high-side and low-side MOSFETs, enabling high efficiency and compact design. With a switching frequency up to 2.2MHz, it allows for small external components, reducing solution size. The LMR33630CRNXR is available in a 12-pin VQFN-HR package with a 3mm x 2mm footprint, ideal for space-constrained designs.
