What turbo? There are so many combinations.

The reason it kicks in (or the intake pressure rises) is that the compressor wheel is spinning enough to make more air go in than the engine can expel. If there is too much pressure then it is let out through the wastegate and/or a BOV.

That's a very, very basic explanation. I'm sure there will be thousands of technical replies soon.
