Something to replace a transformer? Answered

Hi everyone,I just want to know if there's anything that could replace a step-down transformer i.e,Step down 220 volts(AC) to 5 volts(DC).I want a thumb nail sized transformer for my purpose but its hard to get,so if there;s something more compact and can replace the transformer,things would move on awesome!

I'd hack one of the plugtop "mobile phone chargers" VERY carefully - the 5v out will be isolated. The circuits are absolutely minute.
