LMS3655MMRNLR

Voltage Regulators - DC DC Switching Regulators Overview

The LMS3655MMRNLR is a high-efficiency, synchronous step-down DC/DC converter from Texas Instruments. It integrates two power switches and operates with an input voltage range of 2.7V to 18V. The device delivers up to 5A output current with adjustable output voltages. It features a fixed switching frequency of 2.2MHz, allowing for the use of small external inductors and capacitors. The converter includes comprehensive protection mechanisms such as over-current, over-temperature, and short-circuit protection. It is housed in a compact 10-pin WSON package measuring 2mm x 2mm.
