Description

The LM2577N-ADJ is monolithic integrated circuits that provide all of the power and control functions for step-up, flyback, and forward converter switching regulators. The device is available in three different output voltage versions:12V, 15V and adjustable.

Features of the LM2577N-ADJ are:(1)requires few external components;(2)NPN output switches 3.0A can stand off 65V;(3)wide input voltage range:3.5V to 40V;(4)current-mode operation for improved transient response, line regulation, and current limit;(5)52kHz internal oscillator;(6)soft-start function reduces in-rush current during start-up;(7)output switch protected by current limit, under-voltage lockout, and thermal shutdown.

The absolute maximum ratings of the LM2577N-ADJ can be summarized as:(1)supply voltage:45V;(2)output switch voltage:65V;(3)output switch current:6.0A;(4)power dissipation:internally limited;(5)storage temperature range:-65 to +150;(6)lead temperature(soldering,10sec):260;(7)maximum junction temperature:150.
