LM2577 Adjustable Voltage Regulator A Class

The integrated circuit from National Semiconductor is a useful IC that provides all of the power and control functions for a simple(step-up),fly back, and forward converter switching regulator. The IC has a wide input voltage range (3.5V to 40V) and is available in different output voltage versions: 12V, 15V, and adjustable.

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

Package Include:

• 1 x LM2577 Adjustable Voltage Regulator
