    LM2577T-ADJ 3 Pin Transistor SIMPLE SWITCHER-R Step-Up Voltage Regulator


    LM1577/LM2577 Series SIMPLE SWITCHER® Step-Up Voltage Regulator


    Features

    ♦ 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


    Typical Applications

    ♦ Simple boost regulator

    ♦ Flyback and forward regulators

    ♦ Multiple-output regulator


    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 components, these regulators are cost effective, and simple to use. Listed in this data sheet are a family of standard inductors and flyback transformers designed to work with these switching regulators.


    Included on the chip is a 3.0A NPN switch and its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout. Other features include a 52 kHz fixed-frequency oscillator that requires no external components, a soft start mode to reduce in-rush current during start-up, and current mode control for improved rejection of input voltage and output load transients.
