LM2678T-ADJ TI Step-Down Regulator | TO-220-7 | 8A, 1.2-37V

Product Overview

The LM2678T-ADJ from Texas Instruments is a high-efficiency, adjustable output voltage step-down (buck) switching regulator capable of delivering up to 8A of load current. It operates over a wide input voltage range of 8V to 40V and provides an adjustable output from 1.2V to 37V. Housed in a TO-220-7 package, this regulator features a 260 kHz fixed frequency oscillator, soft-start, and thermal shutdown. Its high efficiency (up to 90%) reduces heat dissipation, making it suitable for distributed power systems and high-current applications.
