.LM2576HVS-5 datasheet 

The LM2576HVS-5 (TO-263-5) Buck (Step Down) Switching Voltage Regulator IC provides all the active functions for a step-down (buck) switching regulator, capable of driving 3A load with excellent line and load regulation. This regulator is available in fixed output voltages of 12V version and requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.

The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink and in some cases, no heat sink is required. A standard series of inductors optimized for use with the regulator are available from several manufacturers. This feature greatly simplifies the design of switch-mode power supplies
