Description

LM2577T-ADJ/NOPB Conv DC-DC 3.5V to 40V Step Up Single-Out 11.6V to 12.4V 3A 5-Pin(5+Tab) TO-220 Tube

Descriptions :

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.


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.
