Abstract :
This paper describes a method to identify and assess power loss mechanisms in power MOSFETs for switched circuits. An accurate behavioural MOSFET model is employed in a circuit simulator to analyse the performance of a trench MOSFET technology. A synchronous buck converter for point of load (PoL) applications underlies the study of MOSFETs´ switching behaviour. The methodology aims at the derivation of roadmap targets for future technology developments
