LM2678T-12/NOPB TI SIMPLE SWITCHER® Step-Down Regulator | TO-220-7 | 12V Output, 5A

Product Overview

The LM2678T-12/NOPB is a high-efficiency, 5A step-down (buck) voltage regulator from Texas Instruments' SIMPLE SWITCHER® series. It provides a fixed 12V output from an input voltage range of 8V to 40V. Housed in a TO-220-7 package, this device integrates a 260 mΩ N-channel MOSFET switch and requires minimal external components, simplifying power supply design. With a switching frequency of 260 kHz, it offers excellent line and load regulation, making it suitable for a wide range of industrial and automotive applications.
