220vac in 24V dc out?

Are there any ic's that we can practically design a smps which has 220v ac input and 24Vdc output@3A.

Try PWM controllers available from Maxim. There are few in which accept rectified AC from 85 to 265V. See power supply IC section on www.Maxim-IC.com

Vicor (Vicor.com) makes some blocks that take ~300VDC in (You can use a bridge rectifier and cap, or power factor correction ckt if needed) that provide 24V 8A out.

I like radio21's approach. Unless you want to become a smps (and transformer) designer, it is a whole lot easier to use an off-the-shelf module. It's the d**n transformer design and fabrication that really drives up the cost and pain of even a small smps design.

use uc3842,flyback topology,current mode control

Hello Radio21,

Can you give me the complete URL to Vicor power supply section?

bimbla.

U can try UC3843 or SG3524 with buck or flyback topology

GO TO :

http:\\www.powerint.com

they have complete solutions with different output power
for inputs dc or ac ( 85-265 ).
even they have softwares for that.
I have used some of their solutions.
