Item Specifications and Additional Information:

The LM2577 is a monolithic integrated circuit that provides all of the power and control functions for step-up (boost), flyback, and forward converter switching regulators.

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

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

Typical Applications:
Simple boost regulator
Flyback and forward regulators
Multiple-output regulator
