LM2588S-12

The LM2588S-12 is one of The LM2588 series. The LM2588 series of regulators are 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.

Features of the LM2588S-12 are:(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)Adjustable switching frequency: 100 kHz to 200 kHz; (6)External shutdown capability; (7)Draws less than 60 A when shut down; (8)Frequency synchronization; (9)Current-mode operation for improved transient response, line regulation, and current limit; (10)Internal soft-start function reduces in-rush current during start-up; (11)Output transistor protected by current limit, under voltage lockout, and thermal shutdown; (12)System output voltage tolerance of ±4% max over line and load conditions.

The absolute maximum ratings of the LM2588S-12 can be summarized as:(1)Input Voltage :-0.4V VIN 45V; (2)Switch Voltage :-0.4V VSW 65V; (3)Switch Current : Internally Limited; (4)Compensation Pin Voltage :-0.4V VCOMP 2.4V; (5)Feedback Pin Voltage :-0.4V VFB 2VOUT; (6)ON /OFF Pin Voltage :-0.4V VSH 6V; (7)Sync Pin Voltage :-0.4V VSYNC 2V; (8)Power Dissipation : Internally Limited; (9)Storage Temperature Range :-65 to +150.If you want to know more information such as the electrical AC characteristics ,please download the datasheet in www.seekdatasheet.com .
