LM2586 SIMPLE SWITCHER 3A Flyback Regulator with Shutdown  
Check for Samples: LM2586

FEATURES  
DESCRIPTION  
The LM2586 series of regulators are monolithic  
234  
•
Requires Few External Components  
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 adjustable.  
•
Family of Standard Inductors and  
Transformers  
•
•
•
NPN Output Switches 3.0A, Can Stand Off 65V  
Wide Input Voltage Range: 4V to 40V  
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 regulators. 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.  
Adjustable Switching Frequency: 100 kHz to  
200 kHz

•
•
External Shutdown Capability  
Draws Less Than 60 μA When Shut Down  
Frequency Synchronization  
Current-mode Operation for Improved  
Transient Response, Line Regulation, and  
Current Limit  
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 an adjustable  
frequency oscillator that can be programmed up to  
200 kHz. The oscillator can also be synchronized with  
other devices, so that multiple devices can operate at  
the same 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  
Other features include 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 and cycle-by-cycle current limiting.  
The device also has a shutdown pin, so that it can be  
turned off externally. An output voltage tolerance of  
±4%, within specified input voltages and output load  
conditions, is ensured for the power supply system.

System Output Voltage Tolerance of ±4% Max  
Over Line and Load Conditions
