Description

The LM2577T-ADJ is a kind of voltage regulator. It is a monolithic integrated circuit to provide all of the power and control functions for step-up (boost), flyback, and forward converter switching regulators. It is an adjustable output version.

There are some features of LM2577T-ADJ as follows: (1) requires few external components; (2) NPN output switches 3.0 A, can stand off 65 V; (3) wide input voltage range: 3.5 to 40 V; (4) current-mode operation for improved transient response, line regulation, and current limit; (5) 52 kHz internal oscillator; (6) wide input voltage range: 8 to 40 V; (7) 260 KHz fixed frequency internal oscillator; (8) soft-start function reduces in-rush current during start-up; (9)output switch protected by current limit, under-voltage lockout, and thermal shutdown.

What comes next is the absolute maximum ratings of LM2577T-ADJ. (1): supply voltage is 45 V; output switch voltage is 65 V; (2): output switch current is 6.0 A; (3): power dissipation is internally limited; (4): minimum ESD rating is 2 kV (C=100 pF, R=1.5 k); (5): storage temperature range is from -65 to +150; (6): lead temperature (soldering, 10 sec.) is 260; (7): maximum junction temperature is 150.
