LM2577 - Step-Up Voltage Regulator

Description

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.

Features

  • 1.
  • 23 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.
