LM2576-12V Step Down switching regulatorLM2576 voltage regulator is a monolithic integrated circuit 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 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 theLM2576 voltage regulator are offered by several different inductor manufacturers. Since theLM2576 converter is a switch mode power supply, its efficiency is significantly higher in comparison with popular three terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heat sink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with theLM2576are available from several different manufacturers. This feature greatly simplifies the design of switch mode power supplies. The LM2576 features include a guaranteed +-4% tolerance on output voltage within specified input voltages and output load conditions, and +-10% on the oscillator frequency (+-2% over 0 Degree C to 125 Degree C). External shutdown is included, featuring 80 uA (typical) standby current. The output switch includes cycle by cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
