LMR33620BRNXR TI DC-DC Converter | 12-VQFN-HR (3x2) | 36V, 2A, Synchronous Buck

Product Overview

The LMR33620BRNXR from Texas Instruments is a high-performance synchronous step-down DC-DC converter designed for space-constrained applications. It operates over a wide input voltage range of 3.8V to 36V and delivers up to 2A of continuous output current. The device is housed in a compact 12-pin VQFN-HR package measuring 3mm x 2mm, making it ideal for portable and industrial systems where board space is at a premium. With integrated high-side and low-side MOSFETs, the LMR33620BRNXR achieves excellent efficiency and simplifies layout.
