Introduction

AI Translation

The LM1577/LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), flyback, and forward converter switching regulators. The device is available in three different output voltage versions: 12V, 15V, and adjustable. Requiring a minimum number of external components, these regulators are cost effective, and simple to use.

Features

AI Translation
  • Requires few external components
  • NPN output switches 3.0A, can stand off 65V
  • Wide input voltage range: 3.5V to 40V
  • Current-mode operation for improved transient response, line regulation, and current limit
  • 52 kHz internal oscillator
  • Soft-start function reduces in-rush current during start-up
  • Output switch protected by current limit, under-voltage lockout, and thermal shutdown

Applications

AI Translation
  • Simple boost regulator
  • Flyback and forward regulators
  • Multiple-output regulator
