The MPS8598 seems to be a good prospect, go ahead with it. Now regarding to why use an MC 34063 instead of a 555, it's because it's specifically designed to be used as a switching power supply regulator, and us such it has short circuit protection and a wider range of control that a 555 doesn't simply because it was designed as a general purpose timer. The power supply controller is just an example of its flexibility but having better alternatives at hand (and probably cheaper), I'd go with the specific ones. Then also 34063 are common as dirt, so it's quite probable you will find them easily in Chile too. There are of course better alternatives but they are difficult to be found and need circuit layout knowledge or they will fail. You will find good and tested examples on Mike's site too.
