LM2576TV-ADJ

Product Summary

The LM2576TV-ADJ is a step-down voltage regulator ideally suited for easy and convenient design of a switching regulator (buck converter). All circuits of this series are capable of driving a 3.0 A load with excellent line and load regulation. The LM2576TV-ADJ is available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version. The regulator was designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2576TV-ADJ are offered by several different inductor manufacturers. The applications of the LM2576TV-ADJ include Simple High-Efficiency Step-Down (Buck) Regulator, Efficient Pre-Regulator for Linear Regulators, On-Card Switching Regulators, Positive to Negative Converter (Buck-Boost), Negative Step-Up Converters, Power Supply for Battery Chargers.
