Texas Instruments LM2678S-5-0 is a 5A, 5V fixed output voltage, step-down switching regulator from the SIMPLE SWITCHER® series. This high-efficiency buck regulator operates with an input voltage range from 8V to 40V, featuring a 260kHz switching frequency. The device is housed in a TO-263-8, D2PAK package, facilitating surface mount assembly. Designed for robust performance, it includes internal components for simplified circuit design, eliminating the need for external Schottky diodes due to its non-synchronous rectification topology. Applications for the LM2678S-5-0 span industrial automation, consumer electronics, and telecommunications equipment requiring efficient DC-DC power conversion. The operating temperature range is -40°C to 125°C (TJ).
