LM2585  
SIMPLE SWITCHER® 3A Flyback Regulator  
General Description  
Features  
n Requires few external components  
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.  
n Family of standard inductors and transformers  
n NPN output switches 3.0A, can stand off 65V  
n Wide input voltage range: 4V to 40V  
n Current-mode operation for improved transient  
response, line regulation, and current limit  
n 100 kHz switching frequency  
n Internal soft-start function reduces in-rush current during  
start-up  
n Output transistor protected by current limit, under  
voltage lockout, and thermal shutdown  
Requiring a minimum number of external components, these  
regulators are cost effective, and simple to use. Included in  
the datasheet are typical circuits of boost and flyback regula-  
tors. Also listed are selector guides for diodes and capacitors  
and a family of standard inductors and flyback transformers  
designed to work with these switching regulators.  
The power switch is a 3.0A NPN device that can stand-off  
65V. Protecting the power switch are current and thermal  
limiting circuits, and an undervoltage lockout circuit. This IC  
contains a 100 kHz fixed-frequency internal oscillator that  
permits the use of small magnetics. Other features include  
soft start mode to reduce in-rush current during start up, cur-  
rent mode control for improved rejection of input voltage and  
output load transients and cycle-by-cycle current limiting. An  
±
n System Output Voltage Tolerance of 4% max over line  
and load conditions  
Typical Applications  
n Flyback regulator  
n Multiple-output regulator  
n Simple boost regulator  
n Forward converter  
±
output voltage tolerance of 4%, within specified input volt-  
ages and output load conditions, is guaranteed for the power  
supply system.
