LM2576HVS-5.0/NOPB .

The LM2576HVS-5.0/NOPB is a SIMPLE SWITCHER® low component count Step-down Regulator 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 5V 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 different manufacturers. This feature greatly simplifies the design of switch-mode power supplies.

• Requires only 4 external components
• 52kHz Fixed frequency internal oscillator
• TTL shutdown capability, low power standby mode
• High efficiency
