Product Overview

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
  • Uses readily available standard inductors
  • Thermal shutdown and current limit protection
  • P+ Product enhancement tested
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
