Need the Circuit for SMPS

[xsumirx]

Hello Friends,
Actually After Making my PSU, Today I thought to make a SMPS.
But the Problem is this I have not the schematics of the SMPS. Can anyone here Give me the schematic for designing my SMPS.

My Requirement is below

Input Range Vac(in) :- 100v to 250v
Output Vdc (out) :- +5V, -5V, +10V, -10V

With Feedback Control
Plz post your schematics here !!! I need it  ;D ;D ;D ;D

You may get more help if you provide a proper specification.

You also need to learn how to use Google.

I know how to use Google
I searched too much ...but still didn't find any circuit which matches with my specification.

and I have Posted my Specification:
I need output in both negative as well positive mode

I need 5v positive as well as 5V negative (i.e; -5V)
and +10V and -10V.

If you can help me then plz post a schematic.

Then find one which closest meets your needs and adapt it.

and +10V and -10V.

That's not a full specification.

If you can help me then plz post a schematic.

How much are you willing to pay for someone to design it for you?
