General Description
●The LM2585 series of regulators are monolithic integrated circuits specifically designed for flyback, step-up (boost), and forward converter applications. The device is available in 4 different output voltage versions: 3.3V, 5.0V, 12V, and adjust able.
●Features
●Requires few external components
●Family of standard inductors and transformers
●NPN output switches 3.0A, can stand off 65V
●Wide input voltage range: 4V to 40V
●Current-mode operation for improved transient response, line regulation, and current limit
●100 kHz switching frequency
●Internal soft-start function reduces in-rush current during start-up
●Output transistor protected by current limit, under voltage lockout, and thermal shutdown
●System Output Voltage Tolerance of ±4% max over line and load conditions
●Typical Applications
●Flyback regulator
●Multiple-output regulator
●Simple boost regulator
●Forward converter
