Ajit,

You Could just use Newark Part Number: 76R0066. SYNQOR - IQ32120QTC07NRS-GIQ32120QTC07NRS-G - DC-DC CONVERTER, 12V, 36W. http://www.newark.com/synqor/iq32120qtc07nrs-g/dc-dc-converter-12v-36w/dp/76R0066

If you want to do it from scratch take a look at http://www.intersil.com/data/fn/fn4324.pdf
