need compact power supply for microcontroller ....

i need a power supply for drive microcontroller but without transformer output need 5v 2 amp

you won't get 2 amps without a transformer, at most you can get 200mA with a X1 capacitor that is as big as a transformer ...
what size do you have for your power supply ?
take a look at this one : **broken link removed**

7.0 cm x 3.8 cm x 3.1 cm

You can build a small buck converter to achieved that but what is your input voltage?

You can't beat the generic cellphone chargers as cheap power supplies. But these are rarely more than 1 amp. Are you Sure you need 2 amps?

Maybe a generic tablet charger?

if i used a two charger output connected in parallel
then voltage same current increase it is possible or not.......
and if i connects 5v 2amp to microcontroller what happen then what happens ......damage or not....

No, that's not a good idea. You should be able to get 2A switch mode wall warts, typically used for charging tablets.

But again, are you Sure you really need 2 amps? What loads are you driving with your microcontroller?

Buck convert means
