How to Compute MOSFET Conduction Loss

MOSFET could be used as a switch or amplifier. Regardless of the application, there is a conduction loss. Let’s explore what is the meaning of conduction loss and how to compute MOSFET conduction loss. Conduction loss is the main contributor to MOSFET power dissipation when operating in a non-switching application. Even in switching applications, conduction loss is still very significant

How to Get MOSFET Correct RDSon Value

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.

How to Compute MOSFET Switching Losses

There are two types of losses in MOSFET. One is conduction loss and the other one is switching loss. Conduction loss is explained in detail “here”. Switching loss is not as easy as computing the conduction loss. There are many parameters to consider. You need to understand these parameters to select the correct values.  However, you don’t need any more

Important MOSFET Design Parameter to Consider

The important MOSFET design parameter to consider during circuit design are gate threshold voltage, on-state resistance, current stress, voltage stress, power stress and thermal stress. Threshold voltage refers to the gate to source voltage requirement for the MOSFET to turn on. On-state resistance is the equivalent resistance between drain to source when the MOSFET is on. Current stress is related
