LM2675 - 1-A Step-Down Voltage Regulator

Datasheet Summary

Description

The LM2675 series of regulators are monolithic integrated DC-DC converter circuits built with a LMDMOS process.

These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load current with excellent line and load regulation.

Features

  • Efficiency up to 96%.
  • Available in 8-pin SOIC, PDIP, and 16-pin WSON package.
  • Requires only 5 external components.
  • 3.3V, 5V, 12V, and adjustable output versions.
  • 1.21V to 37V adjustable version output voltage range.
  • ±1.5% maximum output voltage tolerance over line and load conditions.
  • Specified 1A output load current.
  • 8V to 40V wide input voltage range.
  • 260kHz fixed frequency internal oscillator.
  • TTL shutd.
