LM2576HVT-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVT-ADJ is a monolithic integrated circuit step-down switching regulator from the SIMPLE SWITCHER series by Texas Instruments. It operates with an input voltage range of 4V to 60V and delivers a maximum output current of 3A. The adjustable output version provides a voltage range from 1.23V to 57V with ±4% accuracy under line and load conditions. Operating at a fixed frequency of 52kHz, it utilizes a TO-220-5 through-hole package. The device includes thermal shutdown and current limit protection, functioning within a junction temperature range of -40°C to 125°C.
