The Texas Instruments LM2673SDX-3-3 is a SIMPLE SWITCHER® buck switching regulator designed for efficient DC-DC conversion. This component offers a fixed 3.3V output with a maximum output current of 3A, simplifying power supply design. Operating with an input voltage range from 8V to 40V, it features a 260kHz switching frequency. The device is housed in a 14-VSON (5x6) package with an exposed pad for enhanced thermal performance and is supplied on tape and reel. Its step-down topology, positive fixed output configuration, and non-synchronous rectification make it suitable for a wide range of applications including industrial automation, consumer electronics, and telecommunications power systems. The LM2673SDX-3-3 operates across a temperature range of -40°C to 125°C (TJ).
