HI Has any one deisgn and tested an SMPS with below spec
input AC 180-250Vac and output 24V, 500ma. Please let me now if you have design close to it. The preferred controler would be UCC28600.

Either the UCC28600 or the UCC28610 would be suitable devices for this application.
Both devices have design calculator spreadsheets to help with specific design requirements and there are EVMs available for both.
Because our EVMs are targetted for mass market appeal, the EVMs are designed for universal input voltages so they aren't exactly what you are seeking but they can give you a good idea of the device features.
