Product Overview

The LM2673SX-ADJ/NOPB is a SIMPLE SWITCHER® step-down Voltage Regulator with adjustable current limit. The LM2673 series of regulator is monolithic integrated circuit which provides all of the active functions for a step-down (buck) switching regulator capable of driving up to 3A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low on-resistance DMOS power switch. The SIMPLE SWITCHER® concept provides for a complete design using a minimum number of external components. A high fixed frequency oscillator (260kHz) allows the use of physically smaller sized components. A family of standard inductor for use with the LM2673 is available from several manufacturers to greatly simplify the design process. Other features include the ability to reduce the input surge current at power-ON by adding a soft-start timing capacitor to gradually turn-ON the regulator.
  • Soft-start capability
  • Simple and easy to design with (using off-the-shelf external components)
  • Up to 94% efficiency
  • 150mR DMOS output switch
  • ±2% Maximum output tolerance over full line and load conditions
