LM2587SX-5.0

The LM2587SX-5.0 is designed as one member of the LM2587 series of regulators which is 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 adjustable.

LM2587SX-5.0 has nine features. (1)Requires few external components. (2)Family of standard inductors and transformers. (3)NPN output switches 5.0A, can stand off 65V. (4)Wide input voltage range: 4V to 40V. (5)Current-mode operation for improved transient response, line regulation, and current limit. (6)100kHz switching frequency. (7)Internal soft-start function reduces in-rush current during start-up. (8)Output transistor protected by current limit, under voltage lockout, and thermal shutdown. (9)System output voltage tolerance of ±4% max over line and load conditions. Those are all the main features.

Some absolute maximum ratings of LM2587SX-5.0 have been concluded into several points as follow. (1)Its input voltage would be from -0.4V to 45V. (2)Its switch voltage would be from -0.4V to 65V. (3)Its switch current would be internally limited. (4)Its compensation pin voltage would be from -0.4V to 2.4V. (5)Its feedback pin voltage would be from -0.4V to 2Vout. (6)Its storage temperature range would be from -65°C to 150°C. (7)Its lead temperature soldering 10 seconds would be 260°C. (8)Its maximum junction temperature would be 150°C. (9)Its power dissipation would be internally limited. (10)Its minimum ESD rating would be 2kV. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of LM2587SX-5.0 are concluded as follow. (1)Its output voltage would be min 3.17V and max 3.43V. (2)Its line regulation would be typ 20mV and max 50mV. (3)Its load regulation would be typ 20mV and max 50mV. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
