Hello,
I'm looking for an AC-DC converter from 220V to adjustable value from 5 to 9V. Can someone suggest one?
Thanks in advance!

Hi,
The enclosed supplies with mains connector and DC barrel connector tend to only be built for a specific voltage, they are not adjustable. (There are some that are switched between different voltages and sometimes come with a choice of barrel connectors, but they are cheap consumer items, not very good usually). The uncased modules are sometimes adjustable,but only in a very limited range, to fine-tune, using a trimmer resistor, not designed for regular adjustment.
It's recommended to just buy a few enclosed supplies , like 5V, 7.5V and 9V, or otherwise get a bench power supply intended for electronics design, which will be adjustable by nature, in fractions of a volt.
Many, many power supplies fit this description. It would be useful to know your size constraints, budget constraints, how often the adjustment needs to be made, how continuous the adjustment needs to be, how much power/current is needed, how good the regulation needs to be, if you are willing to solve it with multiple modules, etc.
