How to get MOSFET correct RDSon value is the pre-requisite to compute the MOSFET conduction loss or static power dissipation. RDSon is the drain to source on-state resistance of the MOSFET. The term “correct” is relative to the target result. Supposing the target is to compute the maximum power dissipation, then the correct RDSon value must be the worst-case value.
