hi everybody,
i m lookking for a SMPS controller ( PWM IC ) which fixed a 48 volt 0.5 A output. It is good for flyback topology and the input voltage is AC/DC also.
thanks..

 

National Semiconductor has a number of SMPS Solutions for you to choose from.

See if one of them fits your application.

You're in luck. Check www.circuitspecialists.com for their supplies. They have one like that for about $20.00. Just got a flyer today.

 

thank you,
I found LM5021 in national semiconductor. But how can i simulate my design now? Could you give me solution about a design tool which i can put LM5021 in it???
