1 / 32 page LM2587 www.ti.com SNVS115D – APRIL 2000 – REVISED APRIL 2013 LM2587 SIMPLE SWITCHER® 5A Flyback Regulator Check for Samples: LM2587 1 FEATURES DESCRIPTION The LM2587 series of regulators are monolithic 23 • Requires Few External Components integrated circuits specifically designed for flyback, • Family of Standard Inductors and step-up (boost), and forward converter applications. Transformers The device is available in 4 different output voltage • NPN Output Switches 5.0A, can Stand Off 65V versions: 3.3V, 5.0V, 12V, and adjustable. • Wide Input Voltage Range: 4V to 40V Requiring a minimum number of external components, these regulators are cost effective, and • Current-Mode Operation for Improved simple to use. Included in the datasheet are typical Transient Response, Line Regulation, and circuits of boost and flyback regulators. Also listed Current Limit are selector guides for diodes and capacitors and a • 100 kHz Switching Frequency family of standard inductors and flyback transformers • Internal Soft-Start Function Reduces In-Rush designed to work with these switching regulators. Current During Start-Up The power switch is a 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 contains a 100 kHz fixed- frequency internal oscillator that permits the use of • System Output Voltage Tolerance of ±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 rejection of input TYPICAL APPLICATIONS voltage and output load transients and cycle-by-cycle • Flyback Regulator current limiting. An output voltage tolerance of ±4%, within specified input voltages and output load • Multiple-Output Regulator conditions, is ensured for the power supply system. • Simple Boost Regulator • Forward Converter Flyback Regulator Figure 1. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SIMPLE SWITCHER, Switchers Made Simple are registered trademarks of Texas Instruments. 3 All other trademarks are the property of their respective owners.
