产品概述

The LM2674MX-5.0/NOPB is a SIMPLE SWITCHER® low component count Step-down Regulator, monolithic integrated circuit is built with a LMDMOS process. This regulator provide all the active functions for a step-down (buck) switching regulator, capable of driving a 500mA load current with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation (Patent Nos. 5,382,918 and 5,514,947) and a fixed frequency oscillator. The LM2674 series operates at a switching frequency of 260kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Because of its very high efficiency (>90%), the copper traces on the printed circuit board are the only heat sinking need. A family of standard inductors for use with the LM2674 are available from several different manufacturers.
  • Efficiency up to 96%
  • Computer design software (version 6.0)
  • Simple and easy to design
  • Requires only 5 external components
  • Uses readily available standard inductors
  • TTL shutdown capability and low power standby mode
  • Thermal shutdown and current limit protection
  • ±1.5% Maximum output voltage tolerance over line and load conditions
  • 0.25R DMOS Output switch
  • 260kHz Fixed frequency internal oscillator
