Product Introduction

Overview

The LM2576D2TR4-5G is a high-efficiency step-down switching regulator produced by onsemi. This component is part of the LM2576 series and is designed to provide a reliable and efficient power supply solution. It is housed in a TO-263-3 (D2PAK) package, making it suitable for surface mount applications. The regulator is capable of handling input voltages from 7V to 40V and provides a fixed output voltage of 5V with a maximum output current of 3A.

Key Features

  • Guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions.
  • Fixed 52kHz internal oscillator frequency with ±10% tolerance (±2% over 0°C to 125°C).
  • TTL shutdown capability with low power standby mode (80 μA typical standby current).
  • High efficiency and the ability to use readily available standard inductors.
  • Cycle-by-cycle current limiting and thermal shutdown for full protection under fault conditions).
  • Pb-free packages available and RoHS compliant).

Applications

  • Simple high-efficiency step-down (buck) regulators).
  • Efficient pre-regulator for linear regulators).
  • On-card switching regulators).
  • Positive to negative converter (buck-boost) and negative step-up converters).
  • Power supply for battery chargers).
