LM2577 Datasheet Step-up Voltage Regulator

Manufacturer: Texas Instruments

Overview: LM1577, LM2577 .ti. SNOS658D – JUNE 1999 – REVISED APRIL 2013 LM1577/LM2577 SIMPLE SWITCHER® Step-Up Voltage Regulator Check for Samples: LM1577,.

General 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.

Requiring a minimum number of external ponents, these regulators are cost effective, and simple to use.

Key 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.
