IL2576HV-5.0KB-P IC IK SEMI 5V 3A LM2576HV IL2576HV-5.0KB-P

Product Overview

A high-efficiency, step-down (buck) DC-DC switching voltage regulator capable of driving a 3A load with excellent line and load regulation. Operating at a fixed switching frequency of 52 kHz, this monolithic integrated circuit reduces the size of external filter components and features a built-in power switch tube to simplify power supply designs. It converts a wide range of high-voltage inputs into a stable, fixed 5V output, making it highly effective for industrial controls, automotive adapters, and distributed power systems. For enhanced system reliability, it integrates robust safety mechanisms including cycle-by-cycle current limiting and overcurrent protection across a broad operating temperature range (-40°C to +125°C).
