LM2576HVT-ADJ TI Switching Regulator | TO-220-5 | 3.3V-37V, 3A

Product Overview

The LM2576HVT-ADJ from Texas Instruments is a versatile step-down (buck) switching voltage regulator capable of delivering up to 3A of output current. It features an adjustable output voltage range from 1.23V to 37V, making it suitable for a wide variety of applications. The device operates at a fixed switching frequency of 52 kHz, which allows for smaller filter components compared to lower frequency regulators. Housed in a TO-220-5 package, it offers excellent thermal performance and ease of mounting. The LM2576HVT-ADJ requires only a few external components, simplifying design and reducing board space.
