want a schematic for a 20v dc power supply

[bolaryn]

hey guys
i just need a curcuit diagram for my project
a 20v dc power supply without the use of an IC. just zener doides, transistors, resistors, and caapacitors..

This sounds like a job for... Superman!

Actually, it's far more Clark Kent.

I note that you haven't said anything about input voltage, current requirements, why you don't want to use an IC, or what school you go to (since it sure sounds like homework).

hey thanks
tz more like a project.
the input voltage is 240v
nt really sure abt the current requirements tho bur lets jst say 2A
i want to compare the result btw the output using an IC nd without use an IC...
