Product Overview

The LM2576T-ADJ/NOPB is a 3A low component count Step-down Regulator 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 LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a specified ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on the oscillator frequency. External shutdown is included, featuring 50μA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. This monolithic integrated circuit that provide all the active functions for a step-down (buck) switching regulator, capable of driving 3A load with excellent line and load regulation.
  • TTL shutdown capability, low power standby
  • High efficiency
  • Uses readily available standard inductors
  • Thermal shutdown and current limit protection
  • P+ Product enhancement tested
