LMR43620RS3QRPERQ1 TI DC-DC Converter | 9-VQFN-HR(2x2) | 36V, 2A, Low IQ

Product Overview

The LMR43620RS3QRPERQ1 from Texas Instruments is a high-performance, automotive-grade synchronous step-down DC-DC converter. It operates from an input voltage range of 3.5V to 36V, delivering up to 2A of continuous output current. Housed in a compact 9-pin VQFN-HR (2x2 mm) package, this device integrates high-side and low-side MOSFETs, minimizing external component count and solution size. The LMR43620 is designed for robust operation in harsh automotive environments, with features such as spread spectrum frequency modulation for reduced EMI, and a low quiescent current of 2.5 µA (typical) for improved light-load efficiency.
