LMR43620MSC5RPERQ1 TI Switching Regulator | 9-VQFN-HR(2x2) | 36V, 2A

Product Overview

The LMR43620MSC5RPERQ1 is a high-performance step-down (buck) switching regulator from Texas Instruments, designed for space-constrained and power-sensitive applications. It operates over a wide input voltage range of 3.5V to 36V and delivers up to 2A of continuous output current. Housed in a compact 9-pin VQFN-HR package (2mm x 2mm), this device integrates high-side and low-side MOSFETs, requiring minimal external components. The regulator features a fixed 5V output voltage with ±1% accuracy, making it ideal for automotive and industrial power rails.
