LMS3655AMRNLT TI Power Management IC | 22-VQFN-HR（5X4） | 5.5V Input, 5A Output

Product Overview

The LMS3655AMRNLT is a high-performance step-down (buck) regulator from Texas Instruments, designed for space-constrained and power-sensitive applications. It operates from an input voltage range of 2.5V to 5.5V and delivers up to 5A of continuous output current. The device features integrated MOSFETs, low quiescent current, and a high switching frequency of up to 2.2MHz, enabling small external components. The 22-pin VQFN-HR package (5mm x 4mm) offers excellent thermal performance and a compact footprint.
