The LM2577-ADJ IC is a monolithic integrated circuit that provides all of the power and control functions for step-up(boost), flyback, and forward converter switching regulators. The device is available in output voltage adjustable. 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 under-voltage 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:
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
Soft-start function reduces in-rush current during start-up
Typical Applications:
Simple boost regulator, Flyback and forward regulators, Multiple-output regulator.
