General description
The LM2576 series of regulators are monolithicintegrated circuits that provide all the active functionsfor a step-down (buck) switching regulator, capableof driving 3-A load with excellent line and loadregulation. These devices are available in fixed outputvoltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustableoutput version.Requiring a minimum number of externalcomponents, these regulators are simple to useand include fault protection and a fixed-frequencyoscillator.The LM2576 series offers a high-efficiencyreplacement for popular three-terminal linearregulators. It substantially reduces the size of the heatsink, and in some cases no heat sink is required.A standard series of inductors optimized for usewith the LM2576 are available from several differentmanufacturers. This feature greatly simplifies thedesign of switch-mode power supplies.
