Texas Instruments SIMPLE SWITCHER® LM2678SD-3-3 is a high-performance, easy-to-use synchronous buck switching regulator IC. This 3.3V fixed output device delivers up to 5A of continuous output current from an input voltage range of 8V to 40V. Featuring an internal switch and a resonant-mode power conversion, it operates at a switching frequency of 260kHz, minimizing external component count and size. The LM2678SD-3-3 is designed for applications requiring efficient power conversion in demanding environments, including industrial automation, automotive systems, and consumer electronics. Its 14-VSON (5x6) exposed pad package facilitates effective thermal management. The device’s topology is a non-synchronous buck converter, suitable for step-down voltage regulation.
