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

It is my understanding that AAC does not encourage projects of this type. If you are planning to build a low voltage power supply, the only safe way to do so is with a step-down transformer.

There are wall warts that can do this. I would suggest it is not practical to DIY without a transformer, but if it is available off the shelf that is the way to go.
