What are you trying to control with the power supply? How much power does it need? Let us know more about your end application and we'll be glad to point you toward a solution.

likewise do you wish to use discrete parts which are readily available or logic devices or you go for micros.

Are you looking to add timing control external to an existing power supply, reconfigure an existing supply by additing internal timing control, or build a supply from the ground up with timing control? As Joe and Floy said, you really need to be more specific about what you want to do.
