LM2587 SIMPLE SWITCHER® 5A Flyback Regulator
Checkfor Samples: LM2587
1FEATURES DESCRIPTIONThe LM2587 series of regulators are monolithic
23• Requires Few External Components integrated circuits specifically designed for flyback,
• Familyof Standard Inductors and step-up (boost), and forward converter applications.
Transformers The deviceis availablein4 different output voltage
NPN Output Switches 5.0A, can Stand Off 65V versions: 3.3V, 5.0V, 12V, and adjustable.
Wide Input Voltage Range: 4Vto 40V Requiring a minimum number of external
components, these regulators are cost effective, and
• Current-Mode Operation for Improvedsimpleto use. Includedin the datasheet are typical
Transient Response, Line Regulation, and circuitsof boost and flyback regulators. Also listed
Current Limit are selector guides for diodes and capacitors anda
• 100 kHz Switching Frequency familyof standard inductors and flyback transformers
Internal Soft-Start Function Reduces In-Rush designedto work with these switching regulators.
Current During Start-Up The power switchisa 5.0A NPN device that can
• Output Transistor Protected by Current Limit, stand-off 65V. Protecting the power switch are current
Under Voltage Lockout, and Thermal and thermal limiting circuits, and an undervoltage
Shutdown lockout circuit. This IC containsa 100 kHz fixed-
frequency internal oscillator that permits the useof
• System Output Voltage Toleranceof ±4% Max small magnetics. Other features include soft start
Over Line and Load Conditions mode to reduce in-rush current during start up,
current mode control for improved rejectionof input
TYPICAL APPLICATIONS voltage and output load transients and cycle-by-cycle
Flyback Regulator current limiting. An output voltage toleranceof ±4%,
within specified input voltages and output load
