Hello Shruthi,

Just about anyone who makes DC/DC convertor I.C.s will have published designs in application notes and data sheets. You need to know what maximum load current you intend to supply; at lower currents, you can use an I.C. with built-in switching transistor for a lower parts count design. The topology you probably need to use is called a 'buck converter'.

Just have a look around on the websites for National Semiconductor, Micrel, Linear Technology, Maxim, or Texas Instruments - to name but a few.
