The LM2577 is monolithic integrated circuits that provide all of the power and control functions for step-up (boost), flyback, and forward converter switching regulators. The device is available in three different output voltage versions: 12V, 15V, and 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 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.
This article provides you with a basic overview of the LM2577 voltage regulator, including its pin descriptions, features and specifications, etc., to help you quickly understand what LM2577 is.
• 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
