IL2576-XX

TECHNICAL DATA 3.0 A, 15 V, Step-Down Switching Regulator IL2576-xx The IL2576 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step– down switching regulator (buck converter). All circuits of this series are capable of driving a 3.0 A load with excellent line and load regulation. These devices are available in fixed output voltages of TO-220-5L 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version. These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the IL2576 are offered by several different inductor manufacturers. Since the IL2576 converter is a switch–mode power supply, its efficiency is TO-263-5L significantly higher in comparison with popular three–terminal www.DataSheet4U.com linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heatsink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with the ORDERING INFORMATION IL2576 are available from several different manufacturers. This feature greatly simplifies the design of switch–mode power IL2576S TO-220-5L supplies. The IL2576 features include a guaranteed ±4% tolerance IL2576D2 TO-263-5L on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to TA = -40° to 125...
