Suggestion for 220VAC - 9V, 1.5A PSU

[saikat36]

Here I need suggestion/guidance/advice to design a PSU 220VAC~9V,1.5A DC without using most common type step-down Transformers which are heavy & bulky. Actually I don't have a space to deal with.
Mobile charger, Digicam batt. charger, now-days many power adapters they don't have conventional step-down Transformer but have a driver circuit. Can anyone suggest me such type of circuit for my PSU.


Thanks

You need switch mode power supply,

Above links might help you, you may change some parts and design accordingly
