Texas Instruments SIMPLE SWITCHER® LM2679SD-3-3 is a high-efficiency, monolithic synchronous buck switching regulator. This device provides a precise 3.3V fixed output voltage with a robust 5A output current capability. Operating at a 260kHz switching frequency, it utilizes a non-synchronous buck topology, minimizing external component count. The input voltage range is 8V to 40V, making it suitable for a wide array of power supply applications. The 14-VSON (5x6) package with an exposed pad facilitates effective thermal management. This component is commonly employed in industrial automation, medical equipment, and automotive systems requiring reliable voltage conversion.
