    Ive heard that there is a new IC in the market that converts 230V A.C. to D.C. directly. it has all the components built in. has anybody heard of this? If yes can you provide me the details?

    You can do it without IC (and transformer) as well with proper rating of diodes & capacitors, however this is a very dangerous setup as due to absence of transformer there is no isolation.

    There could be an IC, but I think the reliable solution would be using a transformer itself. You should realize that lots of SMALL components are packed in a very less space so generally ICs have a lot of problem with heat dissipation. Using ICs for such high voltage application would be obviously an unreliable solution.

    the idea of this type of ic is not reliable must use transformer.

    Can you tell us why its not reliable ? If we can remove transformer we can make system compact.

    ^exactly. As far as the heat factor goes, it can be controlled by using a heat sink like a normal regulator IC. This type of IC saves a lot of work and it probably is cost effective.

    i agree system must be compact without using txr..but how stepping down of ac can be done without trasformer?

    In cheap systems all that is done is to use a series AC capacitor of correct voltage and capacitance.

    Have a look at the link given by Bioramani of datasheet.
