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

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

TYPICAL APPLICATIONS

•

Flyback Regulator

Forward Converter

Multiple-output Regulator

Simple Boost Regulator
