### **Descriptions and Features:**  
The LM3668SD-2833 is a high-efficiency, step-down DC-DC converter designed for portable applications requiring a regulated 2.833V supply. It integrates synchronous rectification for improved efficiency and operates at a high switching frequency, allowing the use of small external components. The device includes features such as power-saving mode, thermal shutdown, and soft-start to enhance performance and reliability. Its compact WSON package makes it suitable for space-constrained designs.  

(Note: "NS" refers to National Semiconductor, which was acquired by Texas Instruments in 2011.)
