Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LM2673 SNVS030O – APRIL 2000 – REVISED JUNE 2016 LM2673 SIMPLE SWITCHER® 3-A Step-Down Voltage Regulator With Adjustable Current Limit.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM2673 series of regulators are monolithic integrated circuits which provide all of the active functions for a step-down (buck) switching regulator capable of driving up to 3-A loads with excellent line and load regulation characteristics.

High efficiency (>90%) is obtained through the use of a low ONresistance DMOS power switch.

The series consists of fixed output voltages of 3.3 V, 5 V, and 12 V and an adjustable output version.

Key Features

  • 1 Efficiency Up to 94%.
  • Simple and Easy to Design With (Using Off-The- Shelf External Components).
  • Resistor Programmable Peak Current Limit Over a Range of 2 A to 5 A.
  • 150-mΩ DMOS Output Switch.
  • 3.3-V, 5-V, 12-V Fixed Output and Adjustable (1.2 V to 37 V) Versions.
  • ±2% Maximum Output Tolerance Over Full Line and Load Conditions.
  • Wide Input Voltage Range: 8 V to 40 V.
  • 260-KHz Fixed Frequency Internal Oscillator.
  • Soft.
