The LED using, in lighting applications, is becoming more and more attractive and the possibility of using the powerline directly, as a source of power supply, is becoming more and more interesting. Moreover, if the circuital solution allows a compact implementation that can be placed in the same volume of a standard lamp screw, it becomes more interesting.

Switching obviously
The solution is a switching converter, with buck topology, that is able to work with high
