The LM2671MX-5.0/NOPB is a SIMPLE SWITCHER® Power Converter High Efficiency Step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 500mA load current with excellent line and load regulation. This regulator is available in fixed output voltage of 5V version and requiring a minimum number of external components, this regulator is simple to use and include patented internal frequency compensation, fixed frequency oscillator, external shutdown, soft-start and frequency synchronization. The LM2671 voltage regulator operates at a switching frequency of 260kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include ±1.5% tolerance on output voltage within specified input voltages and output load conditions and ±10% on the oscillator frequency.
  • 6.0 Version computer design software
  • Requires only 5 external components
  • Uses readily available standard inductors
  • ±1.5% Maximum output voltage tolerance over line and load conditions
  • 0.25R DMOS Output switch
  • TTL shutdown capability
  • Low power standby mode
  • Soft-start and frequency synchronization
  • Thermal shutdown and current limit protection
  • Green product and no Sb/Br
This 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.
