Product Overview

The LM2676S-ADJ/NOPB is a step-down switching Voltage 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 series consists of fixed output voltages of 3.3, 5 and 12V and an adjustable output version. 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 inductors for use with the LM2676 are available from several manufacturers to greatly simplify the design process.
  • Efficiency up to 94%
  • Simple and Easy to Design with (Using Off-the-shelf External Components)
  • 150mΩ DMOS Output Switch
  • 50μA Standby Current When Switched OFF
  • ±2% Maximum Output Tolerance Over Full Line and Load Conditions
  • 260kHz Fixed Frequency Internal Oscillator
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.
